Asus Rampage 3 Gene Xeon X5675 overclock?

[WooX]

I've been trying to get mine stable for the past 4 months, I'm aiming at 4.5Ghz too, for the last few days I thought I finally got it stable after 11 days with no BSOD but it finally crashed yesterday with KMODE_EXCEPTION_NOT_HANDLED (1e). As far I know the cause should be CPU/Voltage related right? (I attached the minidump in case someone is willing and can get any info out of it).

Today I raised Vcore from 1.4V to 1.40625V and CPU PLL from 1.88V to 1.90V, here's my voltages on BIOS:

Temps usually stay under 60C while gaming and low 50C while using it for work stuff, I think it's almost stable since it took over 10 days for it to crash, I use it for 12~15 hours a day. With your experience can you give me any tips on how to get it 100% stable? or should I just give up on having it at 4.5Ghz?

 

[Mr.Scott]

CPU voltage is a little low and temps are a little warm.
I would fall back to a solid 4.4. You won't notice a difference of 100mhz.

How much more should I increase for stability? I thought under 50C was normal while idle, which temps should I've getting then?

I will see how it behave the next couple of days, it took 11 days to get a crash, after this little boost on Voltage I think it should be fine but in case it does crash again I will follow your recommendations and go with 4.4

looks like your only running in dual channel how many ram sticks are installed? I would suggest getting at least 3 dual rank dimms for triple channel make sure they are installed in only the blue slots also make sure your CPU isn't spiking to X 25.5-X 26 multiplier Mine was, so I had to lock it @ X 23 this was causing random crashes, I would suggest setting the CPU Vcore to auto set the UCLK to half the QPI data rate, X23 multiplier and start with the CPU clock at 4.2MHz then up the BCLK one step at a time until it crashes then back down one then try upping the UCLK one at a time until instability or you reach double the DDR3 speed (DDR3 1800 would be 3600 UCLK). I found anything higher on then 3740 UCLK fails stability test and crashes eventually. 3DMark fire strike, Fortnite and Cinebench R20 are good stability performance tests to quickly expose instability, also use AIDA 64 stability test to check for QPI & ram timing and voltage instability. I found anything over 1.35v on the Vcore gets too hot for anything more intensive than gaming with minimal performance gain unless you are running a chiller for cooling. you should also tighten up your memory timings 1800 should be able to run fine at 9-9-9-24 CR1, I would suggest trying 8-9-9-15 CR1, 8-9-9-17 CR1, 8-9-10-17 CR1, 8-9-10-15 CR1 benchmark for performance and run AIDA 64 ram stability test to find the sweet spot. also find DDR3 memory with an XMP voltage rating no higher than 1.50-1.60v, 1.30v QPI/DRAM, never use XMP overclock or auto voltage for the ram when overclocking

How much more should I increase for stability? I thought under 50C was normal while idle, which temps should I've getting then?

I will see how it behave the next couple of days, it took 11 days to get a crash, after this little boost on Voltage I think it should be fine but in case it does crash again I will follow your recommendations and go with 4.4

some crashes could be video driver or other corruption from random crashes while overclocking I would first try DDU and clean install video driver and make sure there are no other hardware errors in computer management admin event viewer also run admin CMD SFC /scannow and windows memory diagnostic to narrow it down

Yes, I'm running in dual channel, I used to have 24GB with 6x4GB sticks, but since I installed my new cooler (Hyper 212 LED Turbo) last year back when I still had an I7 920 I think might have damaged something on the board (pins maybe?) because the last 2 dimms just stopped working and I had to remove 2 ram sticks, now I'm with 16GB with 4x4GB which is dual channel only due to the last ram dimm being empty. I've had my eyes on new memories for a while but if I don't get the dimms fixed I don't think its worth it, that's the only reason why I didn't changed yet.

I'm running X25 multiplier because like I said on the previous post I've been trying to get it 100% stable for over 4 months now, I've tried X23 multi and with that higher BLCK is needed to get to 4.5Ghz, temperatures were higher than with X25 and a slight lower BCLK. It is not spiking to X25.5 nor X26, it stay fixed on X25, my motherboard is similar to yours it's a P6X58D Premium. I've been using AIDA64 stability test for a while now and it's great, BSODs now happens way less often than when I started tweaking things, at the time of my first post it took 11 days for any instability to show up but unfortunately yesterday I got another BSOD but this time with different code, DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1), as far I know this is not related to CPU Vcore like the last one but with the memory controller.

Regarding the memory timings, mine are rated for 1600MHz with XMP configurations 9-9-9-24 and I running it at 1800Mhz, I was able to have it running on tighter timing like 9-9-9-28 but instability showed withining 5~10 hours of daily use, so I think it's better if I don't push it anymore. Also since the last BSOD might've been memory related I'm thinking about setting lower frequency with tighter timings because I'm at the limit with QPI/DRAM voltages, I don't want QPI over 1.35V and DRAM over 1.64V, what do you think I should do now?

 

[DirtyBiker]

Do you have CPUZ? if so when it boots open it and watch the multiplier mine was jumping up to X25.5-X26 this was causing it to crash with the multiplier set at X25 even with speed stepping, C1E, and C state disabled. I would try tighter timings 8-9-9-17 CR1, 8-9-9-15 CR1 also have you tried a fine cosmetic makeup brush and WD40 on the LGA pins to regain channel 3? also in the ram slots (of course while it's powered off) then clean with alcohol and can of air, clean the back of CPU with tooth paste and toothbrush then clean with alcohol and swab check the LGA pins for bent pins with a microscope or magnifying glass I bought a cheap USB Microscope so I can get a close look at LGA pins. did you have triple channel with your I7? have you tried putting it back in to test? you can also run AIDA64 stability test in the background with all the boxes unchecked it will record if your multiplier is jumping to X 26. try running only 3 dims in the 3 blue slots to see if triple channel works.

 

[WooX]

Yes, I do have it, posted a screenshot of it on my first post. I'm positive that it don't jumps to X25.5-X26, it stays X25 all the time. No, I haven't tried cleaning it since I don't have the correct tools for it speacially the ones you've mentioned. I used to have tripple channel with the I7 but before I installed the new cooler, using Intel cooler box I'm sure that I had tripple channel with 6x4GB RAM sticks, I must have broken something while installing the new cooler. I also already tried 3 dims in the 3 blue sloots, it simply doesn't boot, RAM led keeps on allerting to problems with RAM, I might try cleaning it once again when I replace termal paste soon, but for now I think the only thing I can do to get it 100% stable is to lower RAM frequency to 1400MHz to get tigher timings, if I get BSOD after that I will know for sure its simply not possible to have it at 4.5Ghz with the RAM sticks I have.

Those tools I mentioned are very readily available and cheaply obtained I would try everything to fix the triple channel an intermittent connection with your RAM could be a big problem or if the back plate or cooler are making contact with the motherboard in a way that's causing a short I have not tried overclocking with ram rated at 1.65 volt as that is the maximum voltage Intel recommends so it probably wouldn't be wise to go over that I run 8-9-9-15 CR1 @1866 1.64v read speed is 29000+ MB/s

As far as I know I do know the three main locations for vcore, vtt and dram voltage on the Asus P6X58D-E still haven't found pll voltage point since but from experience the board revision 1.00 I have is damaged cpu socket pins but ran ok for a long time then began to have trouble with it crashing all over the place and board 1.01 is a better performer still had to correct minor connection issue in the socket to cpu since the cpu was involved with smoke and oxidation as some of the pads were coated in some unmovable material like you couldn't scrub it off with iso 99.9% regardless. So ended up lightly sand papered the contacts on the cpu with an emery board just to make the gold contacts shiny than dull looking. As I have Xeon X5675 she might be rough looking, battered and bruised but goes like a clapper

who still uses X58? lets see those benchmarks

 

[WooX]

After over a year and 108 BSODs I finally got mine stable at 4.2GHz. I gave up trying to get it to 4.4 and 4.5, it just wouldn't get stable, 4.2 is the sweet spot for it for stability and good temperatures.

 

[DirtyBiker]

Yeah I leave the CPU voltage set to auto on my board that's 1.35v max QPI/VTT 1.35V MAX DDR 1.64V MAX set the UCLK to the lowest setting above slow mode and the qpi frequency to half the uclk and raise the BCLK as far as it will go stable then lower the multiplier and raise the BCLK until stable then raise the qpi frequency Max stable they're all different it's a silicon lottery I have another machine that I was able to reach stable at 4.3 with DDR3 set at 1866 but the performance isn't near as good as this chip

 

[Toothless]

I think my x5675 was fine thrown in at 1.35v and 4.5ghz. It took over 1.5v for 5.1ghz though.

That is pretty sick. 4500MHz within the stock voltage range. 5.1 at 1.5 is pretty sick too lol
1.6v only got me 4800 on my old X5690 ES.

Was 4.8ghz all core and 5.1 with HT off. Somewhere on the forum I posted screenies.

This CPU lived for years @ 4.2 GHz never been over 1.35v what amazed me is that it's stable withl 3920.4 MHz on the north bridge clock powers the RTX 2080 nicely I undervolted it to 1000mv @ 1950 stays low 60- high 50c in the case with the side cover on

Eh.......you already seen mine.
Nice OC you got going there.

 

[DirtyBiker]

Time for more case mods I want to have the plastic front panel vented below the cooler master logo hoping to have them water jetted need to draw up a cad design I have a local waterjet company hopefully their prices are reasonable if not I may just have to break out the drill this 2080 likes to breathe and when I take off the front panel there's a massive performance increase well maybe not massive but every little bit counts ;-)

Cine bench R15 I managed to top out at 1029 with turbo to 4.2ghz I think I can't remember but these were on 9-9-9-24 timings it was tight enough
Also bonus thing I managed to get TurboV app to work on windows 10 as well used the 4 pin pwm to 3 4 pin splitter to control the top and rear fan using the asus p6x58d-e chassis fan header with github fan control even upgraded the fans to Arctic F14 !40mm fans to get better air flow inside the case

WoW that's a good score for 4.2 my 4.3 overclock can only manage 1008 in R15, how did you get turboV working?

UnCore speed ?

 

[Edwired]

UnCore speed ?

Can't remember might be on screenies somewhere on the Xeon owner club or on my computer as that score was done on the Asus p6x58d-e rev 1.00 before it gave way with damaged cpu socket during the cleaning after the house fire back in October 2021 most of my overclocking settings was on that board. As it could be around 3600 or less but can't be too sure as I was limited by corsair 1600mhz 9-9-9-24 can't remember what model they were

WoW that's a good score for 4.2 my 4.3 overclock can only manage 1008 in R15, how did you get turboV working?

Downloaded Vturbo and extracted all the files and anything that have exe files set them to compatible win 98 and administration rights you have to install them in specific order then process the same order with windows 7 compatible once installed you have to go the the folder where vturbo is located and set that to windows 7 compatible to fix the visible black box that appears on the top left of the screen then it works every time. When I get a chance I can write up a guide with the files for the Asus p6x58d-e as it might work for other boards that features vturbo app. I got lucky to get it working

That would be awesome

Sorry about the delay in writing the guide for using TurboV on windows 10 was flat out busy in the last few weeks

Installing Epu-6 Engine on Windows 8 CP x64

Yes, I made it and it works!

All this working on my system with minor tweaks to get it working correctly without side effects
All you need is the software from Asus and Revo Uninstaller portable which I can provide here

Installing Epu-6 Engine on Windows 8 x64 and Windows 10 22H2 x64​

Yes, I made it and it works!
I used version 1.03.04 from here but this solution should work for other versions of Epu-6 Engine and TurboV.

1. After unzip run Setup.exe as administrator in compatibility mode for Windows 98 / ME (all other options will end up with failure)
2. Unfortunately setup won't install all necessary components so we must do it manually. Go into "Io" folder and run AsIoIns.exe as administrator in compatibility mode for Windows 98 / ME. To be sure it installed proper driver you can also run it in compatibility mode for Windows 7
3. Next go to AsSysCtrlService folder and run AsSysCtrlSrvcIns.exe and AsSysCtrlService.exe in compatibility mode for Windows 98 and then for Windows 7 as administrator.
4. YOUR WINDOWS WILL RESTART AUTOMATICALLY WITHOUT PROMPT AFTER THIS STEP SO SAVE ALL YOUR WORK! From Acpi64 folder (Acpi for x32 windows version) run AsAcpiIns.exe in compatibility mode for Windows 98 and then for Windows 7 as administrator

Now after windows restart you should have working Epu-6 Engine. Overclocking, declocking and especially fans speed control works very well.

Edit: According to HRC and beck comments below doing this tip with 2-3-4-1 step sequence in some cases can give better results.
