Currently my highest stable OC is 4180MHz, my specs are

E8500 (440x9.5) using Cooler Master Hyper 212
Asus P5Q Pro
2x2gb Kingson 800Mhz value ram

I set the vcore at 1.3625v at the bios, 2.0v for the ram and 1.3v for the nb, those are the only voltages I change.

Now I'm trying to achieve better OC, I bought new rams, Corsair dominator 2x2gb 1066MHz

I'm typing this post with my cpu clocked at 4.275 with 1.4v set in bios, I don dare to go any higher than that, but the OC is unstable I ran intel burn test and the residual (norm) don't match, havent really tried anyting else.

Any way to help me achieve better oc? Is it safe to set a higher vcore? since intel lists the voltage range at 1.3625v max.

So what's your cooling solution?Stock cooling?

CM hyper 212 as stated above, lol

What are the current temperature readings of your proc on full load?

What stepping is your E8500? E0 or C0?

Full load temps are around 70, except intel burn test which it will reach 96 and then the thermal throttling kicks in

C0

Wah.. quite high la ur temperature, higher than my kuad...

What is ur fsb and multiplier?

what is your ram divider used at the moment?, i would suggest using a higher tRFC for the rams as all 2gb sticks hates tight tRFC


@bolded part

if a processor is rated for max 1.3625v, would you zap it?

its like saying, a car's specified redline is at 9k rpm, therefore are you going to run at 9k rpm since its listed as 9k rpm

Bad chip or bad RAM? Try to set higher vmch and try again >.<

Don't know who run 1.5vcore at MSI Iron Tech and the processor survive even with crappy tt cooling

that is competition la hamsap kia

Don't think I'll run it at 1.5v, I'm scared already at about 1.4v+ still can't get stable oc at 4300mhz, buying a better cooler and will try again once i receive it.

Hamsap uncle,he said instant dead lah
I tried pumping up to 1.59v real on 45nm and no sudden death and degradation happened

Really gotta try that some time, if really fried my duo time to get quad , or maybe just get e8600, 10x multiplier

running my e8500 4.28ghz 450x9.5....satisfied....he3

May I ask how much vcore you set?

he didnt say instant death leh ah gua

anyways, better to keep it at the recommended vcore for 24/7 user....

u zap 1.59v is not 24/7 ma

vcore set to auto..1.360v

24/7........I think max is 1.4v real,absolute max
I use 1.59v for long time wei,like 3hours each time

I tried 1.65v with my E8200 before
