Help me reach 3.8ghz with e7200 & GA-EP35-DS3L

post #1 of 6
Thread Starter 
Guys,

With my e7200 and Gigabyte GA-EP35-DS3L, I am able to do a rock solid 3.6ghz, but I'm having trouble reaching a prime95-stable 3.8ghz. Even with the following bios settings, prime95 testing @ 3.8ghz will last only an hour or so at best:

CPU Clock Ratio ____________ [9]
CPU Fine Clock Ratio_______ [0.5]
CPU Host Clock Control_ [Enabled]
CPU Host Frequency (MHz)__________ [400]
FSB OverVoltage Control___ [+0.2]
(G)MCH OverVoltage Control [+0.2]
CPU Voltage Control_______ [1.3625v]

Anyone have suggestions for me? I am wary of raising my CPU Voltage above 1.3625 for fear of killing my chip. Then again, the voltage is of course a bit lower according to cpu-z, so am I safe to go higher?

Any other suggestions for how I might achieve a stable 24/7 3.8ghz?

Thanks!

I was having trouble at 3.6 until I put my fsb and spp voltages down to the stock levels that were on the defaults for this chip. I had them at 1.4 fsb and 1.4 spp like I had with my conroe. As soon as manually put both of those to what is stock for this chip bingo rock solid and could definitely go higher, I'm enjoying 3.622ghz and need to go higher myself. Btw I'm at 1.21825vcore in bios, 1.20 in windows.

btw they were at 1.25 spp and 1.2 fsb

Well I have seen this done and I have not had a OC setup before, lower the multi to 8 and up the FSB more and maybe you can get it stable but I have seen it done before and it has HELPED SOME people but not for all people

My third system is an e7200/GA-EP35-DS3L, same as yours. I run the Vcore @ 1.45 for 4-4.5Gig OC's with no problem,
although I am water cooled. As long as these chips are well cooled, higher Vcore isn't an issue. There's even
a member of extreme systems that took his Vcore up to 1.7 on phase change cooling.

Anyway, for a stable 24/7 3.8Ghz OC, I've included pics of all my M.I.T. BIOS settings/CPUZ. Hope they help.

Well, I am becoming less and less worried about raising CPU voltage over 1.3625, having seen many successful examples such as Dryadsoul's. Now I just have to bring myself to do so

try lowering your vcore until it becomes stable, i get 1.15vcore at 3.6ghz and 3.7 all i need is 1.168vcore 4Ghz requires 2.16vcore, but thats my chip. Just because your CPU works for a few days at high volts doesn't mean it wont degrade
