x58 xeon x5675 overclocking help needed with high speed mem

[Edwired]

I know that's strange I thought maybe you were using a USB UEFI boot devise to run NVME M.2 PCIE SSD

No I don't use nvme m.2 pcie ssd as I'm currently running crucial mx100 ssd as my main operating system. I'm guessing it might be an older aida64 at the time and I never spotted that. As it might be a bug in the older adia64 in displaying the details correctly

linus made a video of trying 48 gigs on this board and it ran fine for 48hours straight in tests. idk though. depends on the quality of the board.

anyways for some reason the memory now doesnt wanna run above 1480 or so mhz when set to 2288 xmp. it appears to now ignore anything higher than 10.0.

anyways i'm picking up a cheap 5660 tomorrow to see if that chip has more potential even tho its 1 snitch slower.

for some reason this x5675 refuses to run uncore any higher than 3ghz stable.. pretty sure my old chip did 3.6 atleast

I would set the BLK to the ram speed, set the ram speed to 1333, with BLK at 133, then raise the BLK, the ram speed will go up set it at via the BLK 1900 then lower the multiplier so the CPU target is close to 4.2 Ghz set the QPI to the lowest setting not slow, if the lowest is over 7200 lower the BLK until its as close to 7200, this is as fast as you can run your ram stable. leave the voltages set to auto with load line enabled, manually set the memory voltage at 1.6 or as close to it as you can get, then test and lower the ram voltage as low as you can stable. start with 9-9-9-24 CR1 then lower those one at a time until stable timings change one thing at a time timings first then ram voltage test and repeat you should never use XMP on X58 it will over volt and fry the memory controller on the CPU it may still work at this point but will random BSOD anything over stock speed

That's unconfirmed rumor that some people spread. Makes absolutely no sense. It's hard not to be in 0.5v range.

my Asus Rampage Gene 3 Xenon X5675@ 4300 MHz keeps setting the memory voltage at 1.67v when I set the voltage at 1.6v I have to set it at 1.594 in the bios and it will spike to 1.601v the multiplier is set at 23x and ram is clocked at 1866 with 9-10-9-27 CR2 timings on cheap mix match 4x4 16375 MB of 1600 11-11-11-28 dims I damaged the IMC on one CPU setting the DIMM voltage to auto also not a good idea to enable XMP on X58 it will overvolt the ram as well.

Only way to find out is using the digital multi meter (dmm) on the mosfets that goes to the dimms as asus motherboards have a habit of overvolting. These mosfets have a flat metal on one side use the positive probe on this and the negative probe on the closest screw hole next to the dimm this will give an close reading on dimm voltages. I had the vdimm at1.60v it overvolting to close to 1.64 to 1.65v give or take depending on the load.

Also make sure none of the motherboard jumpers are set to ov mode this give more overvoltage you might have to check the motherboard manual to find them on your board

Yes this board has labeled probe points by the 24 pin connector and the numbers from AIDA64 and bios are accurate

Voltage reading on such high-end board should be accurate. Set the DDR voltage manually, and test stability with software MemTest64 or HCI MemTest.

Can anyone see any potential problems improvement or suggestions here seem to run good 990 cinebench R15 score

Everything looks dialed in to me. At least nothing stands out as a problem. None of your voltages are too high, your clock speeds all look good and if you're stable, 4.29ghz is a very respectable daily OC. I say well done! Silicon lottery seems to have gone in your favor!

 

[Mr.Scott]

It is very good. Almost my daily to a tee. Except I have 2 processors.

Do you only run 6GB per CPU daily on that system?

 

[DirtyBiker]

Well I spoke to soon I don't think it likes the mix of 1600, 9-9-9-24 and 1600, 11-11-11-28 modules from 3 different brands I got bsod and application crashes last I'm gonna try loosening the timings tonight I set them back to auto but there defaulting to 9-9-9-24 which is way to tight for 1866 just purchased a 4x4 1866 kit from eBay today

Most likely the rams causing crashing applications which bsod were you getting

yeah I loosened the timings 9-11-11-27-CR1 its stable now but a big drop in ram benchmark score BSOD was memory related I don't remember I don't use page file so no dump file. I will try tightening it up a little more tried to shoot for the moon HahAhA I'm sure it will like the 1866 kit I purchased, it has the same timings I was getting the good scores, I'm just running this thing on a test bench for now with some junk ram I have laying around just testing this board I've only had it for a week and I like it nicer then my Asus P6X58D-E that one has good 2133 ram in it 24 GB I'm running it at 1866 I'm thinking 1900 is about all X58 can handel 1866 seems to be the sweet spot at least for the Xenon X5675

 

[chaoshusky]

Wow.. I almost miss the days of my X58 system being the daily driver, got many years out of that thing. Though, its interesting to see how increasing the RAM speed only seems to affect the 'copy' aspect and doesn't do much for Read/Write..if anything it ends up about the same or lower! That's why i just used a good 1600MHz kit, tightened the timings (9-8-8-20 CR1) at 1.5v and left it alone! My X5670 happily did 4.4GHz on an AIO at 1.28vCore, only had my IMC clocked at about 2800MHz and got figures pretty close to all these posted ones, as the IMC was much more efficient it didn't have to be double the RAM speed, if i remember right you only 'need' it to be a tickle over 50% higher otherwise there's little benefit - getting it to 3800MHz just made things get really warm with little improvement! I ended up hitting about 4.6GHz if i wanted to push past 1.4v on the core but..nah. And the QPI/Vtt i always kept at 1.2v, not like i had exotic cooling (a big air cooler/AIO is hardly exotic, is it?) but yeah, it's long since been retired. I actually miss the 8086K i ended up with, i hit the silicon lottery jackpot with that one! (5.4GHz no AVX offset at 1.38v) And of course de-lidded it! But i think i need to do some investigating on my current system as these numbers have dropped quite a bit...they're also not that far off the Xeons in terms of raw numbers now are they? Though mine used to easily do nigh on 50GB/s on the RAM before all the Spectre/Meltdown crap, wonder how much it hit the speed on Ryzen with Specter V3?

Yeah I am running with asus p6x58d-e here with x5675 I pretty much found the limit for the blck which I got is 200 so it down to the last few bits of the puzzle relating to the uncore and qpi link. As well running with 6x corsair xms3 2gb 1600mhz these runs with 9-9-9-24. Still tinkering with it since the day I got it

Another P6X58D-E user here, though with Xeon X5650 and 18GB RAM (3x2GB 1600 + 3x4GB 1866) and I'm running at 20x210 atm with RAM at 1680 9-9-9-27-2T. Great board btw, does its job fine as a HTPC.

Running with ~1.4V though I have custom watercooling so temps are fine.

 

[Edwired]

Best I can get with the uncore being doubled of the ram this is with turbo enabled resulting 4.52ghz at vcore 1.336v, Qpi/Dram Core Volt =1.25v. I think the ram is possible holding me back as I can't get it to work correctly if I go to the next multi for faster ram the system would take about 2 reboots before posted but with this ram been selected below it don't do the weird reboots

How did you get the multiplier to 26? mine only Hits 25 and when I enable turbo boost it benchmarks at 25 but in applications it clocks down so I disabled the turbo boost try playing a game and see where you're multiplier is at.

Yo, thanks for reminding, I need to also tune the uncore clock myself ran Prime for 6h yesterday so I guess my X58 setup is stable, usually the errors come in the first hour..

Depends on board, I'd guess. Some boards give a higher multiplier than others. What board do you have?

 

[DirtyBiker]

Asus P6X58D-E but have you checked your clocks on in game benchmark? when I had mine to 25 it would clock down with turbo boost enabled but even with it enabled it would not go to 26 I know the X5675 has a 26 multiplier but I never saw the option in the bios. I also have the Asus Rampage 3 Gene

Ah, the same board which I have on my HTPC. How are your temps?


edit: PERSONALLY I'll go with a lower multiplier and higher bus, haven't tried over 210 yet though.

high 60s low 70s, during cinebench R15 run, side cover on, 2 cores spike to 77-79, but I think that's before the fans can ramp up, never gets near that while gaming, with my RX570 pegged at %100, it might hover around 50-60c can anyone spot the case mod?

I have over 90C in Prime though I have crappy reused TIM even tho I have a custom loop on my Xeon...

 

[Edwired]

All I did is turn on everything in the bios then in the cpu menu where it shows Intel PPM Configuration set it to power optimized then set the qpi/dram to 1.25v and dram bus 1.54v. Then found a cmd file that can add the processor performance boost mode into the power option menu which you can toggle on or off or aggressive or efficient this can be seeing in realtime while monitoring with hwinfo64 you will see how the cpu multi changes along with the clocks once you toggle the menu and pressing apply. I pretty much found this by accident a while back. That how I got the multi x26 to show up as well it can do all core on multi x26. The L3 cache it can be ramdom one as it never dead on point as one minute it shows 107gb/s then it changes it mind then it shows under 100000mb/s after a few runs with aida64 cache and memory benchmark everything else in that stays pretty much the same
