JIUHB 0323 at 2.04ghz (215x9.5) did I go about o/cing this right?

My rig

Athlon XP 1800 jiuhb dlt3c 0323
Thermalright slk900a
A7n8X v2.0 1007 bios
2x256mb winbond bh-5 chips
western digital 200gb se
lite-on 52x24x52
lite-on 16x dvd
Sparkle 120mm fan 300watt power supply


After reading some of the stickies and other users' experiences on overclocking, I bought this system only to overclock. I first lowered the multiplier all the way and raised the fsb as much as I could. I got up to 215fsb x 6.5 multiplier. Then I kept raising the multiplier till 9.5 until it gave me a dead post / no signal to monitor/ screen. I raised voltage .75volts to 1.625 and got it to post. I tried raising the multiplier again with more and more voltage, but the computer will not post and just hangs. Is this the limit of the CPU or is this a powersupply type problem?

Sounds like that is the limit for your RAM not your CPU. Did you incrrease DIMM voltage? If not try that and see if you can get it higher. Is that pc 3700 with the bh-5? If so you should get much higher than that. Mess around with chipset voltages and DIMM volts and see what you can do, if youhavn't already.

Good Luck

that cpu should go higher, something other than the proc. is the problem and like cluinist said probably lack of voltage to the ram...

[Kekkai]

*bump

Ram is being given the highest voltage that my motherboard will allow (2.8v).

What is the typical reason for a black screen post when trying to overclock? That's what I'm trying to figure out... please help, it took so much time and energy to acquire an 1800 dlt3c jiuhb and some winbond bh-5's. I'd really like to maximize what I can get from this with your help.

Is it maybe because I'm trying to run this on tight timings? (2 - 2 - 2- 5)

[brennan77]

OK, lower the FSB a bit, like to 180 or something. And overclock your CPU. That way you isolate the CPU. I've had problems with my board in that it won't allow usage of the 10x and 10.5 multipliers at anything above 200FSB. This is strange as I can run with the specs in my sig all day.

Or it could be that your PSU is simply not up to the job - even if the 300W is a conservative calculated power output, a heavily OCed system AMD or Intel will squish a 300W PSU.

What are your voltages like?

[Kekkai]

I got up to 2.3ghz at 1.675vcore with my BH-5 sticks running at 2.7v (2-2-2-6). My 5v is at 4.83 (eek!) but my 3.3 and 12v are running higher than they're suppose to. Windows crashes here n there and I think I'm gonna need a better power supply to make this rig stable. Thanks for all the help you guys. My games are flying right now.

where did you buy your ram? You have to be careful with that. I got mine from some website a while ago. They claim it was a Samsung PC2700 ram 512mb. When I over clock my CPU (1800 Dlt3c JIUHB), my the computer won't even be stable at 166 FSB. I have to lower my FSB all the way down to 141 and increase my multiplier to 16 then it will be stable. I got screwed by buying my ram from some site and I thought I got a good deal. Pay $65 for it. I guess I just paid for a PC2100 ram.

I'd say you might want to lower the FSB and raise the multiplier a little if waht you want is more mhz. Also might want to raise the voltage a bit, say 1.75-1.825. That should get you higher, plus it should still be safe.
