Should I exchange this 2500k?

post #1 of 17
Thread Starter 
I've been pretty disappointed with my 2500k, and I was hoping you guys could help me out. I currently have it at 4.5ghz with a core voltage of 1.35, and the kick in the pants is that even at that high of voltage, it still fails p95 after a while. I haven't had it fail in hours and hours of gaming, but I also haven't had it successfully run P95 for over an hour. Not only that, but when I restart my computer, it will fail to boot (screen stays black for minutes and minutes) until I kill the power supply for about 15 seconds. Then, it will boot but show me a page of bios info that ends with "Overclocking failed. Press F1 to enter BIOS." Sometimes I knock it down, but I've also just entered bios, changed nothing, saved the settings and restarted and it works. It's a very weird thing.

Really my question is, could the chip I get possibly be any worse? I've been reading a ton of stats on the 2500k and I haven't seen any nearly as bad as mine. I did do a Google search for my batch # (L041B702) and it takes me to the 5ghz club thread here on this board with a member named Farmer Boe stating that his chip is pulling 5.2ghz at 1.46 volts. Mine can't even do 4.5 at 1.35....

Well this sound awefully familiar, i can go to 5Ghz 24/7 no problem without any fails.
The part that is familiar to me is the "overclocking failed" whenever i boot my pc after it has been off.
I just save it and it works without a problem.
First it just gives me blank screen for no reason and after i reset it gives me the overclocking failed crap.
I ran prime95 Blend for 4 hours and i have yet to crash a game.

On the exchanging part, it is in no way defective so i dont see how you would be able to RMA a perfectly fine chip.

It's a problem with how the bios is disabling some of the power gates for the CMOS or something. An ASUS Rep on HardOCP's forums said its a work in progress to fix currently.

Well, turns out I got the same performing chip.

4.5GHz @ 1.344v is just

But look at it this way, your only alternative would be a i7-9xx right? And the HIGHEST you could ever hope to get on that is 4GHz MAYBE 4.1-4.2 if you got a GREAT chip (which by our luck we would not get). So I would say getting a stable 4.5 chip compared to an alternative 4 is going to keep up in the gaming world for a long time. As of right now, almost everything is bottlenecked by my GPU.

That's a bad cpu, i can get mine to 4.5 @stock voltage/ 5.0 @1.365v/ 5.5 @ 1.52v.

Have you tried updating the bios ? I couldn't get above 4.8 before 1204 (Asus Evo)

I had something VERY similar to that. But I fixed it...

All I did was, disconnect the power cable, use the jumper to "Clear RTC Ram" as the manual puts it, then turn the pc on, put all my settings in and voila. Never had the problem since

Your chip doesn't sound THAT bad though.

Never tested, but a guess would be 1.45-1.48v.

I couldn't even get 5GHz stable at 1.56v (great temps tho, and only tested a short time, not like that would be 24/7 anyways )

I hate to say it but your statement is incorrect. Many people run their i7 -9xx processors at 4.0 Ghz +, I personally had my 920 running at 4.4 Ghz stable for quite some time on air cooling. I also have reached 4.6 Ghz + on my i7 970 (check my sig) but I run it at 4.2 Ghz folding 24/7 with no problems. Check the core i7 4.0+ ghz thread as well to see how many OCN members have their i7 9xx chips running that high. Only being able to clock a 920 at 4.0 Ghz and no higher would be a POOR chip, most can reach much higher than that
