adamvjackson 0 Posted September 13, 2002 I'd like to see some software to take advantage of that system... BTW, how much L2 cache do those chips have? Still a .13 micron process, I assume? Share this post Link to post

Admiral LSD 0 Posted September 13, 2002 Until Intel reduce their crazy prices I'm not going to even bother giving their chips a second glance. Share this post Link to post
JP- 0 Posted September 13, 2002 Well ive always wanted to go dual 8) So maybe this can be an option. How much more are xeons than normal p4s of the same speed? Share this post Link to post
Jerry Atrik 0 Posted September 13, 2002 my 2.2's were roughly 300usd each several months ago they arent really any more expensive than the p4's the expensive part is the boards to run em and the special power supply u need. Share this post Link to post
JP- 0 Posted September 13, 2002 I suppose the only boards you can get are made by intel then? So no overclocking allowed Share this post Link to post
Jerry Atrik 0 Posted September 13, 2002 Quote: Until Intel reduce their crazy prices I'm not going to even bother giving their chips a second glance. ummm the amd mp processor (2200) is going for about 221 (oem) the 2.2gig xeon is going for about 257 (oem) i will gladly pay 30 bux a chip for an intel. M4Carbine: yea only intel and serverworks my board (supermicro p4dc6+) has a forced clock function that will let me oc but the chips currently run about 30deg f over oat, and i cant find any supercoolers for the xeons. besides these things FLY! so im not worried about oc'ing Share this post Link to post
JP- 0 Posted September 13, 2002 OK just 2 more questions 1) Whats the HS mounting like? is it like the normal p4 mounts? and.. 2) What memory type do you use with yours? Ive got 512mb RDRAM here and it would be good if i could use that. Share this post Link to post
Jerry Atrik 0 Posted September 13, 2002 yea the hs/fan mounts up like normal... sort of but remember the xeons are 600 pin chips they arent the same overall size so a regular hs/fan wont match the clips. yes i have rambus pc800 (512 also) all in all with hyperthreading turned on, most software screams some of the crappier software (surfcam and mastercam) actually generate slower. i am very happy with this setup.

JP- 0 Posted September 13, 2002 OK sounds good, i might have to go for them. Ive always said to myself that the next system i get will be dual, but i always thought it would be amd as my general feeling was that xeons cost a fortune. But obviously they dont Ill just have to pick out a nice mobo pretty soon as i doubt rambus will be around much longer Share this post Link to post
Jerry Atrik 0 Posted September 13, 2002 the only sucky thing i found with the xeons is that the mobos that use ddr are all server only boards... with graphics and no agp port supermicro, tyan and iwil make workstation type boards but they all use rambus ram i wrestled with that delema for awhile and said "screw it" and got the supermicro (about 570usd) u can get a good deal on a mobo/processor combo i got mine at http://www.micropro.com/parts.htm 1 year warranty on everything and the mobo came with the cpu, hs/fan and memory already installed the cpus, mem, mobo and ps were 1470 ps the ps MUST be a special for the p4xeons and there are only a few cases that fit those types of mobos. (server cases like antec will not work) Share this post Link to post
Admiral LSD 0 Posted September 13, 2002 Strike 2 against the Xeons: Rambus RAM. Thats ridiculously priced too. Thank God Intel are ditching it... Share this post Link to post
Jason B 0 Posted September 13, 2002 I read somewhere that they are switching to 32 bit Rambus, which means that you will no longer have to have a matched pair of chips. Share this post Link to post
Admiral LSD 0 Posted September 13, 2002 The reason why Rambus is handled in pairs (in Pentium 4 systems, Pentium 3 systems based on the craptacular i820 chipset could get away with only one RIMM and one continuity RIMM) is because the i850 (and I believe the i860 too) utilise a dual channel memory interface and you need a RIMM in each channel. Thats how they can claim "800Mhz" and "1066Mhz" when the RAM is only clocked at 400Mhz and 533Mhz respectively. The i850 already supports 32bit PC1066 RDRAM but only unofficially. It's still ridiculously expensive (although thats Rambus' fault for making manufacturers take it up the butt from them with their ghey royalties) and still has to be upgraded in pairs.

Admiral LSD 0 Posted September 13, 2002 Dunno if this is a reliable source of info, it was the first thing that popped up in a Google search: http://www.ebnonline.com/business/news/story/OEG20020910S0056 RDRAM was good technology but since Rambus were greedy it never really go to have its day. Unfortunately the P4 is going to be kind of hamstrung without it but who cares. ^^ The above was written before I'd read the projections for the phase out. Intel will continue with the i850 and PC1066 RDRAM until 2005 (giving them enough time to design a chip who's performance isn't shackled to RDRAM). Share this post Link to post
Jerry Atrik 0 Posted September 13, 2002 rambus shot themselves in the foot by being too greedy. but it's still a good technology Share this post Link to post
Jerry Atrik 0 Posted September 14, 2002 no i have one of the workstation boards http://www.supermicro.com/product/motherboards/860/P4DC6+.htm but go to the rest of the products and u will see that the boards with ddr mem are pretty much server only Share this post Link to post

System Bus Frequency 400 MHz Front Side Bus Level 2 Advanced Transfer Cache The 512-KB L2 Advanced Transfer Cache (ATC) is available with current speeds of 1.80, 2.0, 2.20, 2.40, 2.60, and 2.80 GHz. The 256-KB L2 ATC is available with speeds of 1.40, 1.50, 1.70 and 2.0 GHz. Both deliver a much higher data throughput channel between the Level 2 Cache and the processor core. The Advanced Transfer Cache consists of a 256-bit (32-byte) interface that transfers data on each core clock. As a result, the Intel® Xeon™ processor with 512-KB L2 Cache and Intel® Xeon™ processor with 256-KB L2 Cache can deliver a data transfer rate of core speed multiplied by 32 bytes, reported in GBs. This compares to a transfer rate of 16-GBs on the Intel® Pentium® III processor at 1.0 GHz and contributes to the Intel® Pentium® 4 processor and Intel® Xeon™ processor's ability to keep the high-frequency execution units executing instructions vs. sitting idle.
