Poor Memory Performance in Vista (800MHz)

[nrmsmith]

Just bought a quadcore (Q6600 cpu) bare bones system which is fitted with 800Mhz DDR-2 RAM (2GB). After installing Vista and the NVidia 680 chipset software, Vista rates the Memory with a score of 5.0.

This is particularly poor performance considering that I got a score of 5.3 from my old PC system which was only running 667 MHz (OCZ branded) memory.

So is something not setup correctly in BIOS?

Or is Novatech just shipping this system with very poor performance RAM memory?

play around with your memory timing a bit, you may gain more score if you are running at 4-4-4-12 rather than cheaper 5-5-5-15

but the Vista score is useless, even my Sempron 2800+, 1gig RAM and x1650pro was able to get 5.9 in desktop graphics :roll:

Well I tried overclocking the 800MHz memory fitted by Novatech and the PC would not boot. So I think it is low quality, ie cheap.

I have fitted my 2 x 1GB Crucial Ballistix 667MHz speed DDR-2 RAM that I was using in my last PC. This gave the SAME Vista score (5.0); but I was able to do a simple overclock by 20%. This has boosted the RAM to 799MHz and the Vista score to 5.2 (still lower than the unclocked 667MHz RAM in my previous PC).

So far I have to conclude that the Nvidia 680i SLI chipset is NOT anywhere as fast as the Intel chipset I was using before (Intel 945). I have installed the latest nForce 6 drivers but most of the drivers remained those installed by Vista (with names like Standard RAM controller).

PS How do I change the memory timings to 4-4-4-12?

bios, what motherboard have you got?

bios, what motherboard have you got?
being Novatech bundle, it is probably a relatively cheap Foxconn.

Hi there

Asustek P5N32-E SLI motherboard & Award BIOS. It seems to have been flashed to the latest Asus BIOS (dated 22nd August 07). Board is fitted with latest G0 stepping (low power) Intel Q6600 quad core.

it will be somewhere in the bios, if its like mine -extreme tweaker- overclocking- advanced memory timings.

Is your computer slow?
Vista's performance indexing is flawed anyway.

my ram is 5.3 rating, yet its actually very good (being 4gb)

Just bought a quadcore (Q6600*cpu ('http://www.novatech.co.uk/novatech/products/a561x1y0z1p0s0n0m0')) bare bones system which is fitted with 800Mhz DDR-2 RAM (2GB). After installing Vista and the NVidia 680 chipset software, Vista rates the Memory with a score of 5.0.

I just bought their Executer Q6600 with 800MHz DDR2 RAM and got a WEI score of 5.6 for RAM

myns 5.3? yet its at 930mhz, clearly faster than yours. clearly its flawed, so just ignore it

[Taxation]

mine was rated at about 4.lol
3GB ddr400, admitadly it is old, but vista still flies on it, and there hasnt been any performance hit for me when i went xp to vista
