[TeamAU] GIGABYTE P67A-UD5 Corsair Vengeance 16GB + 2600K with OC results & info

[dinos22]

Hi guys

I did some initial testing, overclocking and tuning and want to share some of the results and findings in hope that it helps some of you get information you need, particularly with the new GIGABYTE Sandy Bridge boards.

I found overclocking fairly straight forward and all the bioses were similar in terms of OC capability. I am on a D1 stepping though so I cant use PLL overvoltage setting you can find in F5x bios (so thats the one recommended for retails).

Ram clocking is pretty good. Once you start to hit the wall a quick bump in QPI/VTT and vdimm does the trick. My chip doesn't like going past 1.24 but there wasnt a need for it as i really only needed to go up to 1.22 in bios for most high clocking runs. Before that high frequency or high capacity RAM clocking will probably require more vtt.

I have also found that overclocking with 2 sticks is better if you install them in slots 2 and 4. This might not be the same for everyone but if you really are trying to push ram, try both configurations and see what works best.

If you are going to be benching and want to push the limits be aware that bios auto recovery feature kicks in very quick with some bioses. If you see that it will go to recovery you can flick the switch on the PSU and clear cmos if you don't want to lose your saved bios settings. Just a heads up.

BTW all the priming was done with the air cooler (before i installed the water) and i can tell you now there was at least a 15C load drop with water and also it managed higher load with ease, i was priming at 5GHz 1.415vcore before i pulled it thinking i dont want this chip to die (at least until i get a better one LOL). This watercooler is awesome for Sandybridge!

There is a mix of a whole bunch of stuff but it still predominantly RAM clocking that's interesting to me at least

Hardware setup:

• GIGABYTE P67A-UD5 (tested F5X, F5e, F5 official, F6a)
• Intel Core i7 2600K
• Corsair H70 Watercooler
• Arctic Cooling Freezer Extreme Air Cooler
• Corsair Vengeance 8GB kit CMZ8GX3M2A1600C8
• Corsair Vengeance 8GB kit CMZ8GX3M2A1866C9
• Corsair Dominator GTX3
• Corsair Dominator GT 2000 C7
• GIGABYTE GTX460OC, 470SOC, EVGA GTX295 (run separately)
• Corsair HX620
• Windows 7 32bit, Windows 2008R2 Server (64bit), Windows XP

I mixed these two kits, not normally recommended by as you can see they are going to run at rated timings even with 4x sticks installed

16GB RAM Test 1866Mhz 9-9-9-27-1T








16GB RAM Test 2133Mhz 9-11-9-30-2T

It wasnt fully stable at these clocks but just reaching them with these kits is pretty good. Volts were a lot higher so probably not something I would recommend on a 24/7 machine with 1.25QPI/VTT and 1.68vdimm

GTX295 for this bench









Maxxmem at 5.2Ghz

27k read yummy

[youngpro]

nice dino those hyper kits fly on this platform 1080+ 7-7-7 with ease,

i dunno why i thought sandy doesnt clock tighter timings so well before, but after testing last week then seeing your results its preety obvious its a nice tight timings platform

[Afrokalle]

WOW

Nice testing and good to see that Hypers fly with Sandy...

1070MHz 7-7-7 is impressive

[dinos22]

yeah it seems VTT does play a bit of a role in overclocking afterall

anyways nice and fast but yeah without properly unleashing the beast with LN2 its still kinda gay. wish we could bench 7GHz+ heh

maybe that Intel grandma can give us some insider tips LMAO

[Sam_oslo]

^ Yeah I think you need a helping hand from grandma for that

I like that AIDA64 27K read, and specially 0.8ns L1-latency, with 2220Mhz 7-8-7-22-1T. SB seams to have a really good Cache, IMC and RAM-improvement.

[dinos22]

This Corsair ram is not too shabby at all

you have some ram over ? Very nice, thx for sharing!

[Johnny87au]

Dino wanna send me 16gb to test , Impressive Maxxmem scores , To bad your using a trial version of everest

[dinos22]

Adding some GTX580 SLI results






Havent checked if efficiency is up to scratch with all of them they "look" ok heh

Awesome results dinos22

Sandybridge is so much fun

[M.Beier]

Must KILL Dino

Jealousy exceeds limit!
Looks good, or wait; Keep that watercooling for yourself (but do send the A0)

[C-N]

@ Dinos22

Great to see SLI running & the 4GB running high & tight, I was wondering how much more bandwidth & latency could be pulled out.

Hi guys

Would you please share some VDimm / Vtt for those 2 setting?

[dinos22]

1.24vtt
1.78vdimm

[George_o/c]

Great results dinos, especially your RAM clocks

How about AquaMark efficiency? I have the same problem with James, can't compare unless it's at the same cpu frequency...

[Yellowbeard]

Glad to see that Gigabyte is not keeping you too busy to represent Team.AU

[dinos22]

bought a retail chip

max clocks 5.3Ghz so pretty average

IMC is decent on this retail

i was close to running 1092Mhz as well but worried i will kill the ram with too much voltage,,,, more with KPs RAMdominance pot

[dinos22]

tightened it up some more and better OS, almost 3 seconds less

this new bios is not too bad

[Deanzo]

Very nice mate, you're making me want to try SandyBridge.

[C-N]

dinos22, thats withe XP & the UD7?? or have you flashed the UD5 with UD7 Bios??

[dinos22]

UD7 and Server 2003

XP SP3 is about the same but freshinstall and lite version


@Deanzo hehehe it's alright but still retarded until intel address this MHz wall BS. I wanna bench this MOFO at 7GHz hahah

[RCG_Bex]

Hmm so these Vengeance sticks not like extra voltage? Damn... was hoping these would be happy for running at a higher voltage for reasonable ammount of time...
