intel core i7 Owners Club

[Tomgang]

all those inputs are totally apreciated, also as you say the fact that you can get the most of your hardware and could have tons of fun, well is something i wish more and more people could try, implement and learn from it, i do something similar but with VGA's, i like to get the most from video cards, if possible OC and tweak, squeeze the most from it!

Thanks for your well made input sir again,

Regards,

I as well oc and tweak GPU as well as memory. But i do not mod my GPU´s to get higher core or power target and such things in generel al throw the GTX 970 i had before is an acception. A GTX 1080 Ti is much to exspensive to risk frying it. as said before i dit get some help mod bios on the GTX 970´s i had. Modet power target in the original bios from 106 % to 119 %, yeah those where some og the cheapest cards out hence the low power target. But its not needed to mod power target on GTX 1080 TI that is al ready 120 % even on the cheapest cards and that is in watt up to 300 watt TDP while stock is 250 watt TDP and you really dont want higher power use than that any way. Some of the more exspensive 1080 TI has power targets as high as 150 % for a gigabyte card out of the boks.

@Tomgang I got myself other MB for my 980X.
And with Ultra 120 Extreme (and Delta Fan on top), I got 4,5GHz at 1,5V.
Didn't tweaked it hard, however I'm testing in WinXP for now.
What do you think ?
Cinebench 2003 : LINK.
I got 125k in 3DMark 03 as well : LINK.
However my main question is for Frequency vs. Vcore : How much you can push your CPU, before you have to ramp voltage a lot more ?
My starts to have Vcore cravings above 4,4GHz.

 

[MrGenius]

3770K + 16GB Team Xtreem LV 2666 + Z77 MPower = Still gets the job done...and then some

Gonna grab me a 2700K soon too. Just for fun.......and a few more boints.

 

[natr0n]

I got this chip today.
2600K on stock volts @ 5Ghz

 

[phill]

I wish my 2600k was that good a overclocker!! It needs a little more volts for 5Ghz

 

[shifter]

3770K -> That was my first I7 My previous platforms were always budget/price/perf. oriented. I've sold it, just to have an excuse for an upgrade not that i really need to.

I7-860 -> still havent assembled it in complete platform, currently i use it for testing on MSI P55-GD55

I7-920 (or 930 not sure) -> came in as a second hand bundle with Asus Rampage II Extreme used it only to update bios replaced the cpu with X5670

Just a thought, when you load the CPU, does the volts change at all?? Seems like a very good CPU...

According to aida64
idle 1.232
load 1.512

Do you think I should try to undervolt perhaps ?

I tried to - offset a tiny bit and no go.

ill pm you in a few days, maybe you can help me to tweak my GTX980 to squeeze a little bit more from it, thanks also again for sharing and help people grow sir,

Here's what mine needed for 5Ghz IBT stable...

I'm not sure I had that good a CPU to be honest.. That said, it was only cooled by a H100i...

A Vcore at 1.5 is high, i think it will degrade the cpu over time faster than you might want it to. According to Intels maximum volt to cores is 1.4 volts. That is why i keep my voltage at 1.41 and no more for 24/7 use.

Se spec datasheet here or screenshot below (its on page 23): https://www.intel.com/content/dam/w...top-processor-series-32nm-datasheet-vol-1.pdf

About Benchmark. Dont use these old ones. They are really not optimized for multicore test or hence test much newer multicore CPU´s. Every test in Cinebench 2003 accept in multi CPU test, all test ran at only one core one thread. These old benchs is from a time when single core CPU´s ruled and dual core where still a rare breed, they really dosent strees CPU to a level that can give you a indication of a stable CPU. I use Intel Burn test to stress test at minimum maximum level and 10 runs. Its very hard on the CPU and temps get pretty high, but testing with this and i have never had a single BSOD or system freeze after a intel burn test and after that i use Prime95 for a long time stress test. If you want to use them keep a close eye on temps cause at some parts of the test CPU can get way hotter than you will exsperience for every day use.

About oc. Volts needed differ from CPU to CPU, silicon lottery you know. But i do have a fif you shut try out. The higher BLCK you use for oc, the more voltage needs to be increased with. I have learn with my CPU that a bit lower BLCK and slight higher multiplier is the way to go with. My cpu hits a golden way at multiplier 25 and BLCK at 177. According to my own at the same voltage at difference in BLCK from 177 to around 185-190 BLCK af lower multiplier can cost me up to 75 MHz before its stable again. So i will try go with multiplier 25 and a bit lower BLCK. That can maybe alow you to lower vcore a bit more. I have also completly dissable turbo mode so multiplier is locket at max 25 and remember to manuel ajust UCLK or Dram Frequency to around 3600-3700 MHz as that will change to and the lower UCLK is the less performance you get and will also slow down your pc a bit if not corrected. UCLK is also the NB frequency in CPU-z in the memory fane blade.

About voltage needed i havent really tryed that much, but can tell at 1.55 volts my cpu can go to 4.75 GHz.

Well try that out and then report back.

I can try and help, but no promises. It depends on how far you have al ready taken it.

stock values, i have never touched this babe!

 

[Tomgang]

Oh in that case there shut be some gain. Maxwell cards tends to have a good head room for OC and generel higher than the newer pascal cards.

thats the main reason! to squeeze a bit more, is a reference 980 !

Oh not the greatest then. Blower style cooler is not great when it comes to oc. Be prepared for more noise then and maybe you will have to use a more agressive fan profile to prevent the card from throttle.

 

[agent_x007]

@Tomgang I used Vdroop enabled option for first try
No droop enabled :

I set 1,4125V in E-LEET.
I assume you used LLC (or Vdroop control) on your board to have the most "flat" Vcore as possible ?

No i dont use Offset or vdrop. Every thing is manuel set to a given voltage and there it is at the hole time. No drops in volts or other things. Volts is optimized to be as low as possible but still fully stable off cause and then i manuel set voltage there and keep it at that.

I use these settings in bios.

 

[agent_x007]

Load Line Calibration on Auto... however going from numbers I think it's Enabled (since Vcore seems close to what you set ?).
I probably won't be able to drop QPI/DRAM voltage below 1,4V (1800MHz+ on 12GB RAM) [it's called VTT on my board ].

well hardware list is epic,
i have stored in office:
i7 3770 + Z68 intelboard
i7 2600 + H61 board
i5 3330 + h51 board
that was my previuos WCG farm, now is offline due maintenance, parts and others for my office and teamwork, stored for now!
im saving some pennies to power on a xeon westmere somewhere arround, does need a board and ram, to crunch,

 

[Deleted member 178884]

@Tomgang making me want to drop the cash on a i7 980x all the time - shame they cost £100 ish and my x5650 costed £20 which is 5 times less.

If you still want tot keep the GPU silent while oc, its a good idea to do so.

Dont get me wrong I7 980X is nice CPU, but if you al ready have a 6 core Xeon for X58 and it oc to around 4.2-4.4 GHz. To be hornestly I7 980X will be a waste of money when it comes to performance. 6 core xeon and I7 for X58 is frankly the same die they are made of. Xeon just has a few ekstra features I7 dosent like ECC memory support and the possibility for running multi cpu konfiguration.

If you ever want a I7 980X or one of the two none X model I7 970/980. Do it because you want to join the I7 club or maybe if your xeon is a poor overclockker and you want to try an I7. Dont do it for performance alone, cause that it more or less the same.

Else there are xeon w3680. That is rebranded i7 980x with unlocked multiplier and every thing, just cheaper than 980x.

 

[phill]

Sound advice there @Tomgang I'm thinking of doing the same for replacing both of my i7 920 D0's just to have 6 cores and doing it as cheaply as possible I do believe both of my Classified boards and even my Gigabyte X58A-OC will take the Xeon CPUs without any modifications

Well 4.2-4.4 is easy as pie for overclocking, I'm currently sitting at 4.62ghz and 1.55v with a alphacool eisbaer 360mm and hitting load temps up to 72c across all cores - I haven't had the chance to push further and it seems to be stable and ran about 20 cinebench runs no prob - will asus realbench it and prime 95 for verification

Yikes 1.55 volts for 24/7 use?

Thats a very high voltage and way over what is reccomended, for a long life span. and yes i have run my cpu at 1.55 as well for 4.75 ghz but that is benchmark only and power use at that voltage is very high as well.

Al throw 72 c at that voltage is great, but i will not reccomend running the cpu at that voltage over longer time. At least not if you esspect the cpu to last long.
