Power supply???

[Ironchef3500]

I recently upgraded my processor from a 1.6ghz to a 2.6ghz, the boards limit. I have not noticed much of an improvement in either 2d or 3d applications. 845 chipset, 768MB pc266, two HD's, two optical drives, Radeon 9700 PRO, Win XP Pro. I am thinking that it is possibly due to a weak power supply? When I was installing the new cpu, I didnt see any rating on the psu anywhere. Does anyone know of a utitily that would test my system and let me know if it is possibly hampering my performance?? Then again how much of an improvement should I have seen with that upgrade?? And yes, all drivers are up to date for everything. I play the usuals, U2K4, Warcraft 3, Halo. To be honest speed seems almost the same... any ideas??

I wouldn't think it's your psu. If it wouldn't cut it you'd prolly have stability problems, instead of slower performance.

I would think that the increase should be noticiable, but I don't play around much with intel products ATM. Somebody who knows better will come along.

It w/b helpful if you listed more specs (mobo,cpu and harddrives), like what kind of processor? For all I know they may be celerons, which I hear suck pretty hard anyway.

Download and Sissoft Sandra, it has a performance diagnotic feature and is free. get it here <A HREF="http://www.sisoftware.net/" target="_new">http://www.sisoftware.net/</A>

Good Luck with it.

Intel mobo 845BG to be exact I think. Processor is a P4 2.6ghz 400mhz fsb. Hard drives are both 7200 rpm, one seagate one WD. DVD writer is a sony, DVD drive is an LiteOn. I have tried that Sandra program, it doesnt have anything about power supply, or atleast in the free version. Anything else?

The bottleneck in your system is the fsb. The P4s are mem bandwidth hogs. You would have gotten more perf from running your fsb sinc with the memory ( 133 fsb) Unfortunately, I dont think your board supports fsb "adjustment"

I didnt even think about that.

Thanks

The free version of Sandra has two parts that may be of interest to you. One is the CPU benchmark, you may be able see the performance delta between your cpu as set up now and the standard. If it works like I suspect it will show you how much performance you are losing cuz of your mobo & ram.

The second part is the tune up or system diag (can't remeber exact name) that may confirm that your FSB speed and ram isn't up to par for that cpu.

Not familiar with the 845BG chipset, but if it supports 200 FSB speed, then you'll need to get some pc 3200 ram instead of that pc 2100


Hmmm... I thought Intel didn't suffer from asynch cpu/ram? Unlike AMD. Well maybe that's if the ram is actually faster than the cpu?

Here's a link to a site that will calculate how much power you need based on the compnents in your rig. It's conservative, so will prolly indicate something larger than is actually neccessary <A HREF="http://www.jscustompcs.com/power_supply/" target="_new">http://www.jscustompcs.com/power_supply/</A>

But if you're looking for a proggy that will actually diag your psu and see how it is performing, well, i don't know of one, sorry

Anyway, good luck with it
