More memory but no more preformance

Frys had a good deal on kingston hyperx 4000 memory this weekend so i go and get a gig of it. (i had 512 of the 3500 stuff) Now i plug it in and ramp the timings up and try to boot at 1:1 @ 250Fsb which the memory is rated for. it doesn boot, so i up the voltage to 2.7 still doesnt boot. I finally get it up to 2.8 and it finally boots and seems solid. But i ran 3d mark 03 and aquamark and got about an 80 point increase in both despite now running at 1:1 and having double the ram.

Maybe these are just bad bench marks for this but it really seems that running at 1:1 and having a gig of ram seems pretty useless for 3d gaming at the moment. I think i might return the stuff for not running at its rated voltage(and costing 240 bucks for almost no preformance gain).
 
I dunno, I never base the performance of ram on 3dmark. Hell I don't even use 3dmark/aquamark. I just fire up the games I always play.
 
It may be unstable enough at that speed that it doesn't cause lockups, but does create errors that the CPU must take time to correct.
 
so do you think it is just cruddy ram? It says its rated at that speed, but it wouldnt even boot at stock voltage. I had to increase it by .15 just to boot though it does seem to run fine now. I played a couple hours of halo but i certainly didnt feel any speed increase. And what is a good ram benchmark to see if im getting cruddy preformance out of it?
 
Well, those ARE bad benchmarks for testing something like this... those benchmarks are more GPU bound than anything else. Try running 3DMark2001 if you want to stick with that type of benchmarking... or try running Sandra or something like that.

About the RAM voltage... I have PC3200 RAM that isn't stable below 2.8 volts either... a lot of manufacturers give their RAM a voltage range... like, 2.6-2.9 volts. Which means, you can safely run it on 2.9 volts if that's what it takes to get it to work, so I wouldn't worry about that.

As far as benchmarking the RAM... you could use Sandra to test the bandwidth and latency... or you could use PCMark2002 to get a synthetic number. I can't really think of anything else that's very memory bandwidth dependant... other than maybe Quake 3.
