Hello

I just bought the following RAM.

4 GB of Kingston HYPER X DDR2 8500 1066 MHZ RAM.

Model # KHX8500AD2K2/4GGR on 2 DIMMS.

I got this at Fry's for $94.99 with a $25 Rebate.

Seemed like a good deal till I got home and checked the latency on this thing.

Latency on this RAM: 7-7-7-20

Kingston Website description:

Description: 4GB 1066MHz DDR2 Non-ECC CL7 (7-7-7-20) DIMM (Kit of 2) Retail
Detailed Specifications: Standard 256M X 64 Non-ECC 1066MHz 240-pin Unbuffered DIMM (SDRAM-DDR2, 2.0V, CL7, Gold)
Mfgr's System P/N's: N/A
Form Factor: Memory Module
Pieces/Unit: 2 (Two 2GB modules, totaling 4GB)
Warranty: Lifetime†


My last RAM was 4GB of Patriot RAM but the latency on it was: 4-4-4-12.

So compared to my last RAM this seems HORRIBLE!! And its actually the worst latency I've ever seen on RAM.

My question is - How important is the latency and will I even notice the difference? I do gaming on my PC BTW.

Thanks,

So no one here knows about latency eh?

My guess is that your patriot ram was also ddr2 800. The timings could be better but the extra Mhz you run the RAM (and maybe FSB too) at will balance it out.
