i5 2500K overclocking
- Thread starter spirit
- Start date
No worries, but yeah, it's a 2500K, doesn't have a FSB lol.Raz3rD said:
Not seen an FSB since the days of the Core 2 Duo/Quad.So, do you reckon I should go for 4.5GHz or leave it at 4.0GHz then? Would adding the extra 500MHz mean that my CPU won't last as long or have a higher chance of frying?
Right OK so now the CPU is at 4.5GHz and stable, but I lowered the VCore voltage from 1.35V to 1.3V and then down to 1.285V and, as expected, each time the temps got lower (good thing). I ran Intel Burn Test on each one and each time it passed, but the temperatures got lower. What is the lowest VCore voltage I should safely go to with an overclock of 4.5GHz? Reckon 1.25V would be OK or is this going to be too low? Are there any other voltages I can reduce to lower my temps as well? Thanks.
Yeah I noticed you had your 2500K at 4.6GHz, what are your temperatures?? At 100% load I'm hitting like 66C - too high?? Recently I've been having a few problems with the PC booting, then dying, then coming back on again - think it's to do with my overclock or voltages? I may up the voltage a bit.
Edit: Pushed the voltage up to 1.3v, we'll see how it does.

the only runs i've done on 4.6 were on a piss cold day with the windows open and the fan on. Temps were high 70s, too high I know, but hey; i did the run. Ambient temp was around 16 degrees C I would say.
Hmm my PC is still turning on, then dying, then turning back on. I'm going to post a thread about it and see if any of the guys here know what the problem might be.
And a cold day in Australia????
Whoa - waaayyy too high!! Try lowering the voltage and the frequency and see what temperatures you get then.Perkomate said:

there was one spike on one core to around 77 or so. Most of the time they were around 72 or so.
As I said, this was just one run to say that I could do it. 4.4 daily now. Now, the fan never gets <75%, ever.
The day was in the middle of winter, in the dead of night. I was freezing my nuts off, but the PC liked it. It's coming into winter now, so I might crank it up to 4.5 for a bit. I'm a little hesitant about more than 1.32 vcore, cause i'm poor and can't afford another CPU and don't wanna risk it.
One thing I did find helped, was to run SpeedFan on the GPU and get that fan up to 100% as well, while not stressing the GPU. It moves a lot more air than just the HSF by itself. Temps down ~7 degrees across the board.

Very little reason to overclock your machine actually. Nothing on that system will make the i5 run 100% for long. I would take the OC off completely, or at the least max it a speedstep setting (i.e. only when needed).

i actually don't agree with it being very little reason. I'm compressing/uncompressing things quite a lot, and it really does help with general system speed. I had it back down to 3.3 for troubleshooting the RAM, and it just felt a little sluggish. It never really clocks up to full speed except for games, and that's where I need the extra power since my GPU is on the budget side.
But hey, i'm an enthusiast, and this is what I enjoy.

That was my point. A 5770 isn't going to properly tax a stock i5.
Reference?

my timings were't quite right. My RAM is optimised for H67 boards (IIRC), so it was default at 9-9-9-24. I changed it to 9-10-9-24, and no problems. Volts went up by 0.005 and that helped too.

Because the expansion of the case (thermal cap) of the CPU is very accurate. Metals expand proportionally to temp, so they know the limits. Intel are pretty conservative though. But anything over 70 would make me uneasy.
