TPU's Core i7 Overclocking and Feedback

[t_ski]

Fit, didn't you post up some EVGA Classified BIOS settings in here? I'm looking for them, but can't seem to find them.

 

[Fitseries3]

i hardly post anything anymore because each board uses different settings really.

i can work up some settings here in a bit if you would like but i've found that the thread on XS has very good recommendations to go by. lots of very experienced OCers in that thread.


the key to OCing i7/x58 is Vcore, Vtt and Vmem. other than that you dont really need to mess with much.

you can also check out the guide on evga forums posted by shamino

Thanks. I was thinking someone here had the Classified and you had suggested some settings to help stability at his speed. I've been home with sick kids the past three days, so I've installed the Noctua NH-U12 (rig is on the tech bench until I get the new waterblock I want) and started OC'ing the chip. This CPU and mobo are working pretty nicely together. I've gone up to 4GHz on Auto, then had to take it up a little in the BIOS to go to 4.2. Trying to get it HT stable on OCCT. 4 thread completes without errors, but checking the "Hyperthreading as Dual Core" box crashed as soon as it loaded up.

Why not tell us your bios settings? I have a classy as well and I've almost hit 4.8GHz on water.

 

[Chicken Patty]

fit, PM me with a price on the RAM if you still wanna get rid of it

CPU VTT Voltage ( +350 )

Thats kinda dangerous bro..

This on your 975?

I never had that number higher then +150. At there it was like 1.32 i think.

You really dont want to go higher then 1.4 on VTT. :\
It was shown to kill yorkfields when raised too much.

I've never seen the Memory Low Gap and Maximum Payload Size. What do these do?

 

[t_ski]

Damn, that was easy:

Haven't even plugged in your suggested settings, Fit.

 

[Fitseries3]

payload is your PCIE load size. video cards run best at max settings but you can adjust it lower in case you have an older pcie device that cannot function with higher "frames".

memory low gap is an allocation feature that allows better performance and stability when running video cards with large amounts of memory. with cards like gtx295's you need to set it pretty high.

i think both of these settings max are 3gb not 4gb.

 

[t_ski]

i think both of these settings max are 3gb not 4gb.

LOL that's what you put, not me!

I'll check them out -thanks

 

[Fitseries3]

thats why i specified it.

 

[Binge]

Yeah, like fit suggested, I can confirm the biggest issue you had there t_ski was your low memory gap. When you get 2xdual GPUs then you need to have it at least at 4GB.

Are you really running TRFC at 110?

OK. That explains it. One thing I noticed with my EVGA p55 FTW is that EVGA is very conservative of auto memory timings...just an FYI. Not sure if it's the same with x58.

I rebooted and made (most of) said changes:

1. Memory Low Gap max is 3G
2. Maximum Payload Size will not change for me - only 128 is available. Does this change when PCIe is set as default display adapter? (Old habit of leaving this set on PCI in case of needing to flash/unflash/reflash PCIe vid card)
3. Left CPU VTT Voltage at +100

Running Prime 95 now to see how stable this is. FYI, my synopsis from XS's Classified thread:

Try Channel interleave 2 way, Rank interleave 1 way, probably break 5ghz

have u tried
setiings

'less'
'less/middle'

and ~ 217 bclk boot with say 106 pcie and then up bclk with eleet?

give more on ioh man and qpi pll, like 1.45, 1.40v
1.45 vcore
1.675 IOH/ICH I/O
1.45 ICH Vcore 1.05
1.45 QPI PLL 1.1
1.8 IOH PLL vcore 1.8
1.8
1.45 IOH Vcore 1.1
1.375 CPU VTT
1.7 DRAM

Ok guys, i decided to push more and see how much further my chip can go. I did two overclock settings, 4.2 ghz with HT on @ 1.29375V and 4.4 ghz with HT on @ 1.36875v. I adjust only Vcore, CPU VTT, and Dram Voltage, all else are on Auto. Please take some look at pictures and tell me maybe i may miss something. Do I need any changes with IOH/ICH I/O or ICH Voltage, or QPI PLL VCore or IOH PLL VCore or IOH VCore?? any tip would be appreciated.

I'm able to boot into windows at 236 with the new S61A bios at 106 PCI-E. Anything beyond 220 used to give me issues.

start with 1,30v for QPI and work your way up from there, 1.45v is not needed in most cases on Evga (or you must be running very high memspeed/uncore clocks).

That, and noobs are rampart everywhere:

"Can I run "X" card in this mobo?"

"Can I run two of "X" cards in this mobo?"

"Does this board work with 920 C0?"

"I am new and I can't boot at yer settings. WTF?"

 

[HammerON]

I need some help with my Gygabyte UD4P. It is different from my EVGA bios and I am rather lost when trying to oc my i7 920. I currently have it stable at 3.67 GHz running WCG at 100%, but I would like to get it over 4.0 GHz:

Don't mind the crapy VGA card

 

[kid41212003]

What I would do are:

Load default optimized setting in bios => Enable Load Line calibration in bios -> Disable Turbo mode -> Reduce memory multiplier to x6, everything else = Auto

Start raising Baseclock until it can't POST -> Start to stabilize your overclock = changing these 2 settings : vcore, qpi vtt => Got it stable without Turbo => Turn on turbo mode and stabilize it again.

I only need to change vcore and qpi vtt to make my cpu stable at 4GHz (prime95). I have the old stepping, and I guess yours could do alot better with lower voltages.
