I think this is pretty hot deal for this memory plus it has pretty cheap shipping.. If you live in Cali you pay 8.25% tax but still not a bad price. I did a search and cheapest I saw elsewhere was 120 or more.... hope this helps someone... sure did me...

How does this compare to the Kingston HyperX PC3000 512MB for $98?

Kingston KHX3000/512 512MB DDR370 PC3000 Memory w/Heat Spreader Retail

Also, the description of the Corsair CMX512-2700C2 mentions:

"Please be advised, Corsair does not recommend selling the CMX256A-2700C2/PT or CMX512-2700C2/PT into dual channel motherboards including Nforce 2 chipsets. For the highest performance and compatibility Corsair recommends using the new TWINX and LowLatence modules."

Does that mean it won't work on Nforce2 motherboards? What's the issue?

It could be power issues. Possibly the newer memory runs with less current, or fewer chips, or both.

so which is better between corsair pc2700 or kingston pc3000?
 
CMX512-2700C2/PT i have 2 stick of this running on a nforce2 without any problems... the whole issue with this ram is something with the bios and spd not setting timings correctly...
 
I have been reading about overclockabilty (<- is that even a word ;-) ) of DDR Memory and this seems to be the best stuff to do it with... that is why I posted it being a good price...


This is supposed to be the top of the line Corsair stuff that is running a 160 to 200 elsewhere...
 
They recommend TwinX because they're tested as a pair, thus guaranteed latency is better. The low latency stuff has a better chance of running PC2700 w/ better timings when running 2 DIMMs. Reason is because the more chips you run, the harder it is to have good timings. I've seen posts in the oc forum and at other sites where testing confirms that running 2 512MB DIMMs on tight timing maxes out around PC2700 (166MHz FSB), I don't think I've seen anyone hit PC3000 (180MHz FSB) with 1GB of DDR. Only really applies to extreme oc'ers though, and even then if you relax the timings your speeds will go up.

Yeah this stuff is great, I bought my stick 5 months ago 170. I'm thinking about jumping on this deal.
 
I payed $165 for the same RAM from Googlegear last fall. I may pick up another stick at that price.

Damn I just bought 2 512 sticks of HyperX PC3000 I have a 12.5x 180FSB OC stable with agressive timings on just one stick the second stick just got here and I have not put it in yet. totally stable now @ 180 FSB but 12.5 is my highest multiplier I'll lose my Mhz if the FSB has to lower due to stablize my ram. Not good 2.25ghz is a nice speed I'd like to stay here 🙂
 
i'm at 175 fastest timings on a 8RDA with my 1 gig... my chip is maxed out and i'm too lazy to change the mult and go for 200 fsb but this ram on a 8K3A+ ran 200 FSB with the timings cranked up also...

can memtest my ram fine @ 215 2.5v and 215 2226 2.7v
 

These Corsairs obviously are not "top of the line," so don't jump at this without considering your options. They say this is CL2, but the full timing is actually 333MHz at 2-3-3. Those timings are CAS Latency, RAS-to-CAS delay, and row precharge time, respectively.

Currently the decision is between the Micron/Crucial 333MHz CL=2.5 for $63, the Kingston 370MHz 2-3-3 for $98, or the Corsair 333MHz 2-3-3 for $100.

The Kingston is guaranteed to work at 2-3-3 at 370MHz, but the Corsairs have brand recognition. I would pass on the Crucial since they only do CL2.5. Keep in mind that if you only need PC2100 DDR, there is a good chance the Crucial will do CL2 at 266MHz.

 

Oh yeah, uh, Xman, hate to break it to you but the RAM is not what's holding you up. These Kingstons are rated 370MHz 2-3-3, and you are maxing out at a FSB of 180MHz, hopefully at a synchronous rate with your DDR, which is 10MHz below what these chips can handle (allegedly.)

Sounds like your CPU has reached its limit.
