Alright first off I'm half way through upgrading my computer.
Sorry if I put this in the wrong thread, but it comes under CPU Memory and Motherboard and didn't know which to pick!
It was a P4 3Ghz (model 530 I think, single core with HT).
I've since used my new parts for a Core2Duo setup with the old processor so I can enjoy a bit more speed before I buy the new proc and video cards.
Motherboard: Asrock P45XE (yes I know its not a great brand, but value for money was great and its a Tom's recommended pick plus has lots of overclocking options and advertises support for FSB2000)
CPU: Old single core P4 3Ghz
Heatsink: Coolermaster NS520 (think thats the model, twin 92mm fans)
RAM: Corsair XMS2 Dominator PC8500 DDR2-1066 1Gb x 2 in dual channel mode
Video card is a cheap 9400GT until I get a HD4890.
Problem A)
Now with the huge cooler and artcic silver being used, I can't get the CPU temp above 40C, it idles in the mid-high 30's. On the stock cooler it idled at 48C and peaked at 74C.
With a 232Mhz FSB its perfectly stable @ 1.385V, but at 233 it wont even post (have tried up to 1.42V but it just wont POST).
I thought it would be funny to see how far I could push it, using the more modern cooling, but 3.5Ghz is the highest it'll go. I also tried increasing the NB voltage, it was 1.14V but I stepped it up piece by piece to 1.2V and nothing changed.
Problem B)
After using the Win7 hardware performance test, my CPU rating went up but my RAM went down. I realised why. Before overclocking the motherboard was running the RAM at 200 x 4 (800 @ CL5). When I overclocked it, the bootstrap (set to auto) lowered it. So I went to manually set it, and the highest I could get was around 964Mhz. So I set that, voltage/CL timings etc were all set using the RAM profile (2.1V 5-5-5-12). Now 964Mhz on 1066Mhz RAM I didn't think would be an issue.
But it would not POST.
Eventually I realised I couldn't run the RAM over 800, not even 880.
So I tried lowering the CAS to 4-4-4-12 with the clock at around 765Mhz, wouldn't do that either, which really suprised me, tried 2.2V and 2.3V as well, just wouldn't do anything.
The memory name in the BIOS comes up as 'DDR2-1066', so I know its not normal CL5 800 RAM.
None of the heatsinks get hot, the only one that gets warm to the touch is the north bridge heatsink. If the system POSTs, its completely stable (well I can play games for hours etc).
So my questions are:
- what's going on with the old P4 chip?
- is the RAM effected by my old CPU? does the really low FSB being multiplied by the motherboard likely a cause for the stuff up? and is CAS4 @ 764 too much to ask for RAM that is CL5 @ 1066?
