AMD X6 1090t + asus m5a88 v evo overclock help?

post #1 of 9
Thread Starter 
hi,

recently i bought my budget rig that was built from

AMD X6 1090t
Asus M5A88 V-EVO
Kingston hyperx 4gb 1600mhz
Sapphire hd 6850
Hyper 212+ for cooling set at max RPM.

After did a lot of reading about OC'ing 1090t until im bored of it, i started my first step to OC this rig, I upped the setting of multiplier*CPUref=18*200=3.6Ghz, i nvr changed anything else, and it worked fine, with the p95 stress.FYI, i disabled C1E,CNQ,and TUrbo core.

then i increased the setting to 3.8Ghz=19*200, at this stage i set my cpu vcore to auto, and i got this FATAL ERROR from P95 stress test, it said something like this," FATAL ERROR: Rounding was 0.5, expected less than 0.4 ", i searched all over the net and read some and heard that the problem can be overcome by increasing CPU/NB voltage, so i did that and it was fine. tested out well with p95.btw, is this the best solution for this problem? do u guys hv any other solutions?

then, without wasting time i upped the muliplier to 20*200=4ghz,since i heard that 4 ghz is easy for this chip...unfortunately the result was too bad,
my comp boot and get bsod while loading wiindows 7 64 bit, i upped the cpuvcore, from auto to 1.44, it boot well but BSOD for less than 2 secs while stressing with p95, i upped the cpu vcore even more to 1.45, same thing happen no change, BSOD comes after 5 secs running p95, i set the cpuvcore to 1.5v which is rarely happen, the the stressing hold to few minutes and BSOD. then i change setting of the multiplier*cpuref=16.5*240, still BSOD no significant improvement, btw, the core temps showing is about 33C idle and 52C while stressing,

then with the 4ghz target, i tried to manipulate other settings:
Cpu Multi:20
Cpu ref:200
Dram freq:1066 and 1333 and 1600
Cpu/nb;auto and 2600 and 2800
HT:2000
cpuvcore:1.45-1.52
cpu/nbv: 1.35
dram voltage:auto and 1.65 and 1.65

i put a very high voltage on all settings but the results change in very small changes.

so my question is what is the best setting to get stable 4.0ghz?am i missing something for the settings?

Ok. First, welcome to the site!
Second, good on you to take on the task to OC your CPU!!

Just a quick n dirty OC help.

Ok. So, first, you want to just adjust one component at a time, small increments at a time. Basically, slowly raise your multi 1-2 steps at a time towards the freq you want.
Always set voltages manually, dont leave in auto. For pretty much everything, CPU, NB, Dimm etc.
C&Q off, C1E off.

Actually, I'd try for highest NB OC first, then CPU. Try to get the NB as close to 3k as you can.
Then CPU.
Like, x18 for 3.6. Stress test for a bit. OK good? !
Then bump to x19 for 3.8, stress test for a bit. Ok good? !
Now your at x20 for 4Ghz, stress test for a bit. Ok Fail? !
Ok, failure. What is your voltage? 1.44v? Ok. Do a small bump. 1.47 for example. Stress again!
Fails? Bump a little again. Repeating process over and over until you find the magical voltage needed for the OC that you want to acheive.
However, if you get to hot with the voltage for the OC you want. Well, then either get better cooling, or your just gonna have to back down the OC to a stable, but cool OC.

Once you have the Max OC of your NB. Then work on CPU.

Always keep HT at 2000+/- ~100.

Set your memory timings to factory defaults of the chips. So, if there rated at 9-9-9-24 @ 1.5v. set them to that for now. OC memory once you have a stable CPU and NB OC.

thx very much,

btw, when you said about failure for stress, is it BSOD? if yes then I'll understand. cause sometimes people confused me that BSOD is memory related.nvm, one more thing, if 1.5v is the voltage, isnt it too high?wouldnt it fry my cpu eh?

For your 1090t you should be able to get 4.0Ghz at about 1.4-1.5 volts stable using the multi. You want about 2800 nb and 2000 Ht link. But this depends on the mb almost more than anything thing else. And the 1.5 volts he's talking about is your Memory. You should set your Voltage and latency for you memory Manually.

thx very much,

my memory w/o oc is 9-9-9-24 with 1.65v, which is 1600mhz actually..

by following Rebelord's steps, now im at approaching 3.8ghz which the settings are :
multi:19
cpuref:200(def)
cpuv:1.425
cpu/nb:2800
cpu/nb volt:1.25v
ht:auto(should i set it to 2000mhz somehow?)
htvolts:auto
dram:9-9-9-24(1600mhz)
dramvolts:1.65

the dram settings are according to factory.

Your Memory should be running at 8-8-8-24 1.65v Check the timings in this link.
http://www.tigerdirect.com/applicati...453&CatId=4533
Nb voltage should be set to 1.275-1.3 @ 2800
Multi @ 20 1.45v which will give you 4.0
Ht link to manual and set to 2000
leave the ht voltage on auto.

This should help you get 4.0 out of your rig as well as make it snapper.
Gl Hope this helps.

thx very much, btw, your link lead me to cl8 model, but mine is cl9,
dun worry about this i got it confirmed on the kingston's page somewhere.

btw, lastly i knew what was blocking me away for this long, it was the llc(load line calibration), after i chg it from auto to enabled, the cpu stressed really well.

now im planning getting a new cooler replacing my hyper212+, what cooler is recommended guys? or should i just add some hyper speed fan attached to my hyper212+?

With a push and pull fan setup on that heatsink and some good thermal paste you will see a nice drop in temp. See what the cfm's are on the fan you got and get 2 that are a little better.
