Seeing If I can get past 3.15Ghz with a Q6600

[JLewis187]

EVGA 750I FTW
Q6600
CoolerMaster 690 case
on Sli if that matters

Right Now Im at 3.15ghz

Vcore - 1.425 (1.376v in Cpu-Z)
Fsb - 1.4
Ram - 2.1 (corsair cm2x1024 - 2gigs 128bit EPP) 4-4-4-12-1T
Spp - 1.45
NF200 - 1.20

I have not had alotta luck geting stable stuff past 3.15, so I decided to not even mess with it, But if you guys have any recomendations on how to go about it, Ill defintly give it a shot and hope for the best.

if you get a better cooler (if your running on stock right now) then that will probably help you get to to 3.2 without any change, other than that, i would just have to say raise the voltage.

I have ocz vendetta 2. very nice cpu cooler as well as artic silver 5. The CPU isnt the problem I just need to know exactly which voltage to turn up, fsb, spp, nf200.. Which would be the best and at which ghz.

each chip is different. to OC a cpu, the Vcore is what you want to step up. if it is already at 1.425, i wouldn't go any higher than 1.45v. the FSB voltage will help with the memory controller, the ram is a bit high for standard ddr2, but not unheard of.

you shouldn't need to worry about the other voltages at all

2.1 vlts is not high for ddr2 ram, for me i go to 2.2, 2.3 is pushing it, also try ur fsb voltage at 1.5 mine is and im at 3.6 on a thermalright 120 ultra extreme@1.384 vlts under 100% load, prime 95 24hrs stable

What mobo are you using? I too have a Q6600 that's giving me crap. I had it @ 3.2 but it wasn't stable so I started the overclock from scratch but it can't seem to run P95 longer than 15 minutes. Currently my Cpu core is reported at 1.392 under load w/ FSB set to 1.4. My mobo is a 780i and it only allows FSB voltage increments of .1 v and 1.5v is highlighted in red, which makes me nervous. SPP is 1.40, MCP is 1.500, HT(SPP<->MCP) is at 1.20, and DRAM is at 1.85

@JLewis187:

I don't know how you're achieving 3.15 but my previous 3.2 OC was using a 1600MHz FSB with an 8x multiplier. After thinking about trying to increase the FSB voltage I had an idea and dropped my FSB down to 1440 MHz and upped the multiplier to 9x which gave me an OC of 3.24. I kept the same voltages and my comp has been running Prime95 for over an hour now with no errors.

My Vcore is 1.36875 for a 3.4GHz OC, your Vcore seems a bit high to me. DRAM @ 2.00v, MCH@ 1.3v.

A 680i LT, i know cheap board, NB-1.5 or 1.4vlts, FSB 450, CPU Voltage under 100% load 1.368vlts(sorry made a mistake above), FSB voltage 1.5 or 1.4 (prime used 1.5 but 1.4 seems ok, no probs, and of course things like C1E are disabled, DRAM 2.20 @ 900 (4-4-3-4-2) (all dimms are filled thats why its 2T)
