Pentium 4 3ghz ... enable or disable HYPER-THREADING ?

[susie]

BJ_M,

So what's your opinion? AMD or Intel.

Does AMD cpu run all the softwares out there that are designed for Intel CPUs ???? (Intel has a huge PC market share)

amd will run anything -- the cpu's are great ... but right now i have to give intel the slight edge (goes back and forth) , the 875P intel chipset with a 3.2 really is a stable fast combo .... the asus p4c800 motherboard is highly regarded ..

i would like to get a amd64 (im still thinking about it - with a nvidia3 150 chip set) but 64 bit drivers are scarce and not mature, the winXP beta 64 is pretty incomplete (and now pretty old) and most apps dont take advantage of 64 bit yet .. you can only run nvidia video cards with 64 bit drivers (and the matrox 450) , you cant even use a ati card with winXP 64 .. you MUST use 64 bit drivers with a 64 bit OS ...

lots of pro software is .... autocad , CCE , main concept , Pro-E , vegas , maya , softimage, photoshop and many more ....

I have been trying to find out if solidworks supports hyperthreading, any idea BJ_M

not it seems (doesnt use smp) -- biggest gain is using a wildcat graphics card (openGL)

2x Xeon 3.2 GHz w/ 1 meg L2 Cache (IWILL DPI533) $2543
Athlon FX-51 (ASUS SK8N) $1465
Pentium 4 3.2 GHz “Extreme Edition” (Intel 875PBZ) $1494

No gaming benchmarks, just workstation-oriented applications.

Notice the dual barton is cheaper than the single CPU systems (A64 FX-51 / P4 EE 3.2ghz)

Ok.

Now let me ask you about LCD monitors.....better choice than CRT monitors ?

I was window shopping at BestBuy and Futureshop and noticed that all the LCD monitors display text very blurry.

amd will run anything -- the cpu's are great ... but right now i have to give intel the slight edge (goes back and forth) , the 875P intel chipset with a 3.2 really is a stable fast combo .... the asus p4c800 motherboard is highly regarded ..

[BJ_M]

future shop turns the brightness up to much usually ... but quality in lcd's can vary .. i really like them myself ...

the Megavision MV173 1280 x 1024 Silver 17" LCD Monitor at best buy has a good picture and is very well priced .. also -- picture quality with a lcd looks better with DVI than with an analog connector ..


look for lcds that have 500:1 or better contrast ratio and .264 or better pixel

check out what you are going to buy IN the store and make sure no dead pixels ...

Bummer, I am about to get a 3.2Ghz P4 at work, mainly for use with solidworks, it would have been nice if it suported HT.

[BJ_M]

maybe next version - because in next version they are dropping support for winME and 98se...


i just read this off thier web site -- i know next to nothing about product ..

but on thier forum they say they do not support dual and HT very clearly

[Kevin abq]

Use Task Manager performance tab to check quickly if you have HT. It'll show up as dual CPUs:

BJ_M can you point me in the direction of their forum, I have not had much luck finding it.

Are those the two HT Xeons? Which board are you running those on? I've been looking into spending a f'ton on a new system and wondered how the two HTs performed with each other, and more specifically if SMP aware apps are seeing all "4" CPUs.

[tdowning]

about the LCD's:

If you have a digital LCD and you run it at it's native resolution, the text should never be blurry.

I can think of three things that are to blame for the blurry text on LCD's:

first off, running an LCD at less than native resolution will cause the pixels to become dithered, so most pixels are showing a blend of two adjacent pixels on the same line. they are likely running the monitors at 1024x768 which is what most people run them at.

second, the third-party monitors are usually being fed by a single computer, by way of a VGA splitter/amplifier, which may very old and of low quality.

third, there's always the possiility of jitter when the signal is converted from digital to analog and back. if the sampling clock isn't dead on you will get jitter.

look at the notebook computers, they should give you an idea what a good LCD looks like. Even ones that have analog interfaces are better simply because everything has been tuned to produce the best quality. The Apple LCD panels are all digital, and look pixel perfect.

some apps see all 4 (like the one im running in the pic (digital fusion) )

that is a IBM intelistation Pro (which uses a MSI board http://www.msicomputer.com/product/detail_spec/product_detail.asp?model=860D_PRO&search_text= ) its a very stable motherboard with good features but now older ....

http://www.msi.com.tw/program/products/server/svr/pro_svr_detail.php?UID=465 is a more up to date motherboard if you dont need scsi .. i require scsi myself (they have a lot of other dual xeon boards as do tyan (very good)


almost all the time i leave HT off ...

i also have (had) a 4 xeon system sgi540 --- but im no longer using it and gave to someone else in office that runs autocad on it now ..

[rallynavvie]

I'm assuming the quad Xeon was running a Linux kernel? AFAIK Windoze doesn't support anything more than 2 CPUs. Which also makes me wonder why it can handle two HT CPUs with HT enabled. I'm a bit confused now

I have a Tyan board, the old Athlon MP workhorse 2460, and love it. I've pushed its specs well beyond what it was meant for (Tyan only supports it up to MP 1900s) and it has never given up the ghost. I'd get a Tyan board for Xeons but they're feature-laden when I don't need a lot of that onboard stuff. Actually someone recommended the Intel SHG2. It's obscenely cheap at $133US which is what kinda makes me wonder what's wrong with it. It has ATA/100, U160 SCSI, 6 DIMM slots , dual LAN, 3 PCI-X slots, and I believe onboard sound and video. So what's going to be wrong with that one?

[BJ_M]

The quad Xeon runs windows 2000 adv. server , which supports up to 32 cpu's

It also can dual boot into a special non-retailed version of Win NT4.0 workstation that supports 4 cpu's (on many things - NT4 is the fastest over all windows versons)

win xp pro supports 2 cpu's with HT (appearing as 4 cpu's - as in the pic above)

is there any way to change the multiplier, I have a CPU which is underclocking, as in one of the posts by me, with sub "Something terribly wrong ...".
The system clock is 200 MHz and the multiplier shown is 8 ie 1600 MHz, but the CPU is 2.8 GHZ.

What can be done ??



Saurabh

[BJ_M]

depends on the motherboard .. most xeon motherboards do not allow any adjustment (re: overclocling or changing any of theose settings)

[saurabh_fzr]

That image was copied from your post here mine is as below



I have D865GLC intel motherboard.

The CPU is underclocking, how to set it right ?

[BJ_M]

in the bios , you set it ... except in some cases , with jumpers (and in some cases , jumper PLUS bios)

have you done this yet ?

when you update a bios - you must (in some cases) set bios to default settings after - then reboot and set everyhting correct.


i dont know that motherboard , is there jumpers on board to set speed?

you can download the manual at intel site if you dont have settings ..

[rallynavvie]

Whoa, did you disable HT and try checking the speeds again? Do that before you start messing with jumper settings.

BJ_M--
Actually now looking at the Asus PP-DWL Xeon mobo. You know how hard it is to find a dual Xeon board with AGP 8x and 64-bit PCI slots? I've got a SCSI host adapter so I thought I could get away from the expensive boards with onboard SCSI but then none of the ones with an AGP slot had 64-bit PCI slots for the host adapter and MPEG card. I was thinking two 2.8 Xeons with the 533 FSB would be nice for most anything I can do. It also accepts unbuffered memory so I can get back up to 2GB of RAM cheaper than how I had to on my current box. I never enabled the error correcting on it anyway

[saurabh_fzr]

I DID IT

I DID IT

Found a jumper which took me to the configuration mode of the BIOS and there I changed the multiplier, got 2.8 GHZ.

But with it came another problem, whenever I use some CPU hungry application the CPU temp starts increases, I have installed a hardware Monitoring software by intel, which starts screaming.
Normally it is around 43 deg but rises to 70-75 deg, the moment I turn off the application it returns to normal.

What can be done to increase the cooling any suggestions.

[BJ_M]

1. clean the cpu fan and the heat sink
2. apply proper thermal grease between cpu and heatsink (if you have never done this - ask someone who has ... as you can damage your cpu and/or socket ...


3. get a larger heatink/fan plus #2 above

75 is high , under full load (100% for all cpu's) - even for days at a time -- 50 would be the max i would see ...

im using stock heatsinks and external fans (its done a little different in a IBM workstation, the fans dont mount on the cpus/heatsinks, same thing with the sgi)
