HP XW8000 - Switching from Prestonia CPU to Costa Rica CPU
I am running a XW8000 with a 533 FSB Xeon, and I thought I would try a 800 FSB xeon. NO this does not work, got beep codes and a blank screen. So this would also mean that the XW8000 will not run a 64 bit system, as there are no 533 processors with 64 bit support.
HP XW8000 - Why so many memory slots?
Why is there room for 12 GB of memory on a system that will only do 32 bits (Max 3.6 GB), I belive server 2003 will use more memory than xp, and some linux distributions will take more memory but with xp you are stuck with 3.6 (see below, there is actually 4GB installed, but its doesn't all show)
HP XW 8000 - Noisey Fans / Fan Noise
When I first switched on my XW 8000 I nearly had a heart attack the fans are pretty noisey. There are the two processesor fans which arn't too bad. The main culprets are the case fan (120mm) and the psu fan.
HP XW8000 - Noisey Case Fan
Here you have two options you can use speed fan to lower the rpm of the case fan, which is very sucessful and almost removes noise all together. OR. You can replace the fan. I have swapped the original for an Arctic cooling F12, which really is silent ie no noise what so ever.
HP XW8000 - Noisey PSU Fan
No option to control fan speed here, so replacement is only option, this is a kill or cure stile manuver and void all warrrenties and you might get electrocuted learn how to swap psu fan here..
HP XW800 - Using a SATA hard disk drive.
You can only use SATA with a PCI expansion card, which I have not tried. The XW8000 comes set up as default to run on SCSI drives, of which it can take several.
It does have ide socket on the maib board, and I am running mine with a ide 7200rpm drive which works fine. If you do opt for SCSI drive you need the 68 pin ones not the 80 pin ones. SCSI does improve the performance but is VERY noisey.
HP XW8000 - Dual Core
No the the XW8000 xeon processor is not dual core, it is single core with hyperthreading, with two processors running task manager will disply four CPUs but this is just an expression.
HP XW8000 - Performance
Solidly quick but not overly snazzy. Pretty good under heavey loads, and when multitasking. With my other PC there would be waiting periods where you could have a rest, but now they are gone, I have never managed to overloasd this machine, you can runs scans, back ups, defrags and works with documents all at the same time.
HP XW8000 - 64 bit?
No I don't think so, max FSB support is 533FSB, 64 bit instruction sets start at 800FSB for 604 socket xeons. I have tried an 800 FSB CPU in my XW8000, doesn't work, and you can't adjust the BIOPS to make it work either!!
