1) P4C800-E Deluxe


2) Intel Pentium 4/ 2.8E GHz

800MHz FSB,

1MB L2 Cache,

Hyper Threading



which of these memory modules should i buy. i know that the motherboard states that it can run Dual Channel DDR400/333/266 Max 4GB(PAT). but your compatability giude states that that mother board can run

the DDR500(PC4000) type ram if i overclock my machine. my question is which of the ram types i am listing below is better suited to run with the mobo and cpu i am buying?




here are the memory modules i am looking to buy but i dont know which would be more stable.


i am looking for system stability i dont know much about overclocking or if it is safe. i have a thermaltake volcano 7+ i can use on the processor.

LOL! They do?


XMS3200XL is Rated at DDR400 @ Cass 2-2-2-5

XMS4000 is rated at DDR500 @ Cass 3-4-4-8

I am not sure the CPU you have will be able to run at 250 MHx but you are welcome to try it! However, I would still suggest XMS3200XL over XMS4000 as they will support a wider range of settings and will out perform XMS4000 at lower clock Freq.


Here are some reviews!

PCstats.com Poll

"PCstats.com asked its readers a simple question; "Who makes the best DDR memory on the planet?" At the final count, 23,734 votes were cast in the poll, and the company that came out on top was Corsair Memory.

Corsair has once again shown why it is a leader in the enthusiast memory industry. When most other companies had completely given up on 2-2-2 modules, Corsair was searching for a way to bring them back. By working closely with Samsung, Corsair has done just that. The new XL line marks the return of 2-2-2, and it's not a temporary return. I can't wait to see what else Corsair does with these and other new memory chips in the near future. Golden Bear Award – 9out 10



In conclusion, the Corsair TwinX1024-3200XLPRO delivers on its promise of ultra-low latency operation of 2-2-2-5 at 400MHz DDR, and it does it with panache. Although they are not very overclockable, they are certainly fast and they look good. If you are looking for the fastest PC3200 dual-channel memory kit, the Corsair TwinX1024-3200XLPRO is certainly it!

Corsair XMS 3200XL Pro (2-2-2-5) Dual Channel Memory Video Review #453:

"The Corsair XMS 3200XL Pro is Dual Channel Memory with low latencies of 2-2-2-5 at 400MHz DDR, a unique specification resulting in excellent performance. Something else that's different about this memory is the 18 activity LED's which indicate memory activity. When combining performance, reliability, compatibility, & a lifetime warranty, it's unbeatable. Watch the Video to find out more..." ~3dGameMan.com



Corsair has really created a package to serve the consumer the best of all worlds. Disappointment is one thing you won’t feel after buying and using this memory. Thumbs up to Corsair for being the first to produce a memory module at DDR400 with 2-2-2-5 timings. These memory sticks bring low latency and high bandwidth together to create a high performance memory. Kudos’ to Corsair.



I think Corsair have proved once again why they are considered one of the premiere suppliers of RAM for the enthusiast community. And not only does the RAM perform as advertised, with the Activity LED’s it looks damn cool doing it! Add to that the fact that a newbie can slap this into his newly purchased mobo, set the BIOS to use the no-brainer SPD settings and bingo! He’s running in the same yard as the Big Dogs! So regardless of who you are, when you are looking for the best RAM for your box, take a good hard look at the TwinX1024-3200XLPRO. I do not think you will be disappointed.



Corsair TwinX 3200XL Pro memory went above and beyond what it said it would do. For the first time that I have been reviewing I’m going to give a 10 for the Corsair TwinX 3200XL Pro memory. It has out performed any memory on the market. Scored 10

With the XL Pro series, Corsair has once again upped the tempo when it comes to producing top quality, high performance DDR modules. Their new line of X-treme low latency PC3200 DDRs, the XL series, will definitely be a benchmark for everyone else that will be following into their footstep. Equipped with extremely good looks via the innovative heatsink and activity LEDs, the TWINX1024 PC3200XL PRO not only provides speed but also ultra performance as well. Thanks to its X-treme low latency timing, the PC3200XL PRO will bring out the best at DDR400 and beyond."




Where PC3200XL excels (yes, I know that’s a terrible thing to say) is in offering a balance between superb latencies and good overclocking capability. Paired with the Athlon 64 we see that processor coming with 10% of its theoretical maximum bandwidth. If you’ve got lower quality or generic RAM you’re wanting to replace with something a bit more stable and a heck of a lot faster, this might be exactly what you want. Compatibility is also good—we tested the PC3200XL in several temperamental motherboards known to have compatibility issues and it performed flawlessly in each—and at its specified latencies.



In conclusion the Corsair TwinX PC3200XL is nothing short of the fastest memory we have tested here at OcPrices. As well as having the tightest timings at DDR400 speeds, it also performs better than virtually all PC4000 we have tested at DDR500 speeds – a huge achievement. Editors Choice




Corsair hasn’t been one to disappoint and this is certainly no exception. I was impressed by the lights on the heatspreaders, this not only looks good but is also a sort of diagnostic tool. If the lights aren’t on, you know something’s wrong with the memory, I like that. At stock speeds Corsair definitely take the crown in performance due to their extremely low latencies. I was also surprised that it could get to 215MHz on these timings. It may be pricey but in this case you get what you pay for. That’s solid performance, a lot of memory (1024MB) and all the bells and whistles. Rated 9/10
