Need Advice From The Experts

[jshake]

After many hours of testing , I was able to move up from 4.5Ghz to 4.7Ghz using various combinations of Mult./ FSB to get a stable 20 min. Prime 95 blend run.
At present , I have not done a 2 hour run of Prime95. Does anyone see , from my attached pic, anything that would indicate possible problems that would prevent using this as a 24/7 overclock.
Also , On a side note , I have been looking at the Swiftec H20-220 Ultima HD cooler as possible upgrade to my Corsair H100I. Cost verses Performance , is it worth the extra money to consider this as a upgrade.
Thanks

I would rather see this done with the fsb up around 235, you have what looks to me like 2133 ram and i think that it would give more favorable memory speed.
or you might just raise you ram speed in the bios.

Thanks,
I will go back and give it a try.

Second attempt

This is the results after changing mult. to 20 and FSB to 235. I was able to move ram speed up 1880. The next setting up from there was 2192 , That exceed the rated 2133 of the ram. You do not think that voltages and temps at this overclock are to high. This was still stable on 20 min run of Prime 95 blend.

that all looks good to me.
2192 ram is sure better than 2133, use it.
try it with the vcore reduced 2 clicks.

then go read this thread

jshake your temps look fine, how did you come up with that Cpu V core? Is it on auto or did you set it there? I'm asking because I run mine 24/7 @ 4.7 and I'm only using 1.45 with Cpu LLc on Ultra high, which sends it to 1.46 ish under load. All chips are different but it seems a bit much.

 

[caddi daddi]

mandrake, buddy, you have one of these cpus, take it away!!!!!

 

[jshake]

I got that Vcore using 1.48 cpu volts and llc set to extreme. It took that to get stable and not drop cores while running prime 95. Anything below 1.54v and I would drop cores. I did not want to run 1.54v all the time, Only under full load.
I will move ram speed up to 2192 and see if I am still stable.
Thanks

jshake, all 3 of the cpuz captures in post #4 are of the cpu tab. Not of memory and spd also.

Sorry about that,
Here are the three different tabs

next up, cpu/nb and ht up to 2500 or so.

 

[jshake]

Tried to move cpu/nb and ht link up to 2500 from 2350. Instant fail would not boot into windows. Dropped back down to 2350 and all is well. I have tried to move cpu/nb and ht link beyond 2300 before with same result.
Thank

[caddi daddi]

ht link is no real issue, nothing to really be gained there.
try setting your cpu/nb voltage to 1.3.

 

[jshake]

Thanks, That seemed to do the trick. I moved cpu/nb up 2580 and left ht link at 2350. I was able to boot into windows without a problem. I was able to Run Prime 95 blend for 20 mins. with no fails or dropped cores.
Attached is the last Prime 95 run.

 

[caddi daddi]

now bring the ht link up to match.

now bring the ht link up to match.

I do not particularly like using Extreme on the Cpu llc, it overshoots the voltage by way too much for my liking. You may want to drop it down to Ultra High and then bump the Cpu V core up a bit and start testing. You may be able to run it at 4.7 under load at a lower V core then the LLc is is bringing it to. Most processors will be able to pass prime at X mhz if they are at lower temperatures with lower V core then they would at higher temps. I know mine does, I would bet that part of the reason I can get away with 1.46 under load is because my core temp under prime for two hours at 4.7 is only 43 and socket is 50 where yours is 52 and 64 respectively. Again I still feel the LLC at Extreme may be overshooting by too much. Just because it's going to 1.54 under load doesn't mean it needs that much to be stable.

+1 mandrake.

 

[jshake]

Thanks Again

Thanks , Caddi for all your help. Was able to move ht link to 2580 with the increase to cpu/nb from1.25v to 1.30v. Made all the difference.
I guess all that is left now is to do a 2 hour run of Prime 95 blend and start benching.

 

[caddi daddi]

you really need to follow mandrake a bit to work on that vcore.

 

[jshake]

I set the llc to ultra high and high with over current at 130%. Then started with a vcore of 1.48v under load it went to 1.50v. I dropped a core at 12 mins in a Prime 95 run. I then moved the vcore up to 1.49 and retested. I dropped a core at 16 mins. I then proceeded to continue the same proceedure until I was at a vcore of 1.52v , under load moved up to 1.54v. At that point , I did not drop any cores. I then went back and set llc to Extreme again and lowered the vcore back to 1.48v. Retested again , under load , moved up 1.54v and was still stable. The reason I am using Extreme setting is it allows me to keep the vcore at 1.48v during normal use and only move up 1.54v when it is under full load.
Thanks
