New System check please+ Mem low CAS vs High speed

[vanderStoep]

I`m in the proces of ordering new PC/ components and building it myself.
Please advise on the components I`m looking to buy
- Intel PIV 2.8 Ghz 800fsb
- Asus P800 deluxe (i865)
- 2* 512mb Kingston HyperX PC 3700 Cl3 (Kit)
- Zalman 400 W PSU
- Pioneer slot-in DVD
- Thermaltake Xaser III case
- 2* Maxtor 120 GB, 8mb Sata HDD (Will be running RAID)

Bringing over from my old pc:
- CL soundblaster audigy
- Cl Soundworks Dtt 3500 - Speakers
- Asus 52*24*52 CDRW
- Iiyama Vision master 454 19 inch monitor
- Asus Geforce 5900 Fx
- 40GB Maxtor HDD IDE (backup)
- PIV Waterkoelingset

Use: Gaming, internet, Will be overlocked

The most doutfull I `m about the memory. It is not on Asus` aproved list and I read several users complain about hyperx 3200 on the Asus mobo although there were no problems in anand`s test.. Furthermore I `m doubting between Kingston HyperX pc 3500 CL2 and this Kingston HyperX pc 3700 CL3 . Of course the pc 3700 will reach higher but it is only CL3. Any advise on this?

I tried to find a review with lower CAS setting@ low speed vs Higher CAS setting @ high speed but I fail to find this. ( only different CAS @ same speed)

Personally, I would get the PC3500. The PC3700 is more expensive and isn't rated that much faster. I'd rather save some money and run at cas 2.

Also, I'd probably go with a 2.4C. It will overclock a lot better than the 2.8 as well as save you some more money.

I`m tied to one certain shop. Price differences between the 2.8 and 2.4 is $80 and between the Kingston modules is $ 20 in favor of the PC 3500.

The PC3500 CAS 2 will probably overclock and might run at 3700 speeds but with CAS 2.5 or 3 or something.

I haven't done any speed testing recently, but the last time I ran speed vs. cas these were the results:

Taken from an Epox 8k7a (AMD760, just to show the age) Memory was 256mb of cas2 pc2100.

145 @ cas 2 was benching the same as 155 @ cas 2.5, in both terms of memory bandwidth and a few synthetic tests (3dmark2k1, etc)

These are far lower speeds than you're looking at, but perhaps they can at least give you some information to work with.

The 3500 CL2 is the better bet.
