Help with increasing RAM bandwidth - Page 2

post #11 of 17
Ok, gonna throw a couple things out there. First off, bench it totally default, and I mean BIOS "load optimized" or standard defaults. If the bandwidth is still low then, then I can only think it's a either crappy RAM, crappy chipset, or some combination of both. If the bandwidth does go up after loading defaults, don't touch the RAM timings. Refresh rates can have a huge impact on bandwidth, so don't change that. Also, while at stock, if it's not set by default, trying setting the RAM command rate to 1T (it'll be either 1T already or 2T). That should also yeild a nice increase in bandwidth. Secondly, does your motherboard supposrt dual channel RAM? I would think it would since it supports 800MHz FSB chips, but your RAM is running in single channel, so check your manual and make sure you have the RAM in the right slots to activate dual channel.

Thanks for the info. I've run it on "fail-safe" (read: stock) before, and it also had crappy bandwidth.

Dual channel: I don't believe it does. It's a cheapy complete with APG 8x. I only have two DIMM slots anyhow so I couldn't possibly get them wrong.

Time for my dirty secret; this computer was originally a pre-fab from Fry's. At first, all I wanted was something with a decent processor and an AGP 8x or PCI-e for a video card. Then I got the computer nerd fever and here I am, a case, power source, a gig of RAM and video card later wanting to OC and play some of the "hotter" games. So I have a crappy pre-fab type of MoBo a decent processor and a terrible bandwidth bottleneck holding me back. Looks like I'll be buying a set of PC4000 1-gig OCZ Golds and hope it's not the chipset.

I agree, but my dirty secret forces me into the new MoBo PLUS Windows option instead of just a new MoBo. If I have to get a new MoBo I'll get one as a last resort... damn Bill Gates.

Oh yes the XP activation, you can ring up and do that just tell em you hard drive failed, remember to back up all your data tho

A new mobo would give your CPU and RAM a new lease of life, skt478 is still good for quite a while yet so a good cheap abit mobo would be ace

Good idea with one flaw...

If my hard drive fails on a licensed version all I have is a miserable format/pcdoctor BS disc, not an install disc. Any idiot could think that one out fast enough to catch the lie.

Pardon my n00bness if I'm wrong about anything.
