Problem with X2 and Windows XP

[Fireskull]

Im sure ive seen this problem on here before but damn if i can find the post on search lol, my problem:

Put in the X2 to replace a 3200+, windows recognised it fine as dual core in task manager etc all fine, but this windows install was slow so i was planning to fresh install on a Raptor im trying, after a days messing around with that, nothing but problems with SATA and XP on this board lol so now ive got XP installed basic copy not even SP1, install sp1/2 etc all updated, check speedfan and cpuz and task manager performance bit and they all only show 1 Core? any ideas? in device manager under processors there both there, anyone know what i have to do? or why it has done this lol? anything to do with just installing bog standard xp? i know it had problems with large hard drisks but Dual core probs?

Please Help lol

 

[Fireskull]

Yep both installed

 

[Fireskull]

Go to ' Device Manager ' and make sure it says ' ACPI Multiprocessor PC ' under ' Computer '

Not at my pc atm but i know it definatelly dosent say multifprocessor PC, it does say sumit about ACPI though, i did try to uninstall this then restart pc and see if that made any difference but no :/ this must be an XP driver or something somewhere as it i put the old HD back in its dual core on XP lol :/

 

[Fireskull]

Don't try and uninstall the driver, select :

'Update Driver'

'Install from a list or specific location'

'Don't search, I will choose the driver to install'

You should now get 3-4 choices, you want to select ' ACPI Multiprocessor Pc '

Kool will try this in half our, hope it works

 

[Fireskull]

No!

only got 2 damn choices what the hell!

Standard PC

or

Advanced Configuration and Power Interface (ACPI) PC

Are you using the latest BIOS revision for your motherboard?

A8N32-SLI was released pretty early, probably before X2 was released and thus early BIOS probably won't recognise X2 correctly.

yea got the latest bios, but as i said in my OP my other XP install works and sees both cores fine, ive just done a fresh XP install and it aint recognised both cores

 

[Fireskull]

Yea fully updated to SP2, although the xp disk is only xp pro standard without even SP1? did the original xp support 2 cores? but then again why hasnt it updated :/ and ive done the update from windows site aswell ive got a feeling im going to have to fresh install on my old 3200+ then put in the X2, which is a pain with watercooling lol

 

[Fireskull]

Hey again, think ive got it, found a site that tells you to press F5 when when it asks for disk drivers etc, then you force it to be ACPI Multiprocessor PC and it continues with install and all is ok now, well apart from Speedfan is only showing 1 core temp but not too botheres as CPUZ and XP showes 2 cores now, also i used Nlite and splipstreamed SP2 and used that so not sure if that fixed it either or if it was just the F5 jobby but either way i hope its fixed now :d ty for all the help guys

 

[Fireskull]

Ty dude coretemp worked a treat, does this cpuz screenie seem ok?

 

[Fireskull]

dono why users still use None sp2 disks download one or buy one (sp1 lower is an virus hazzard as well as some simple things do not work)

if you can see two cpus in task man or in device manager all is good

Nice overclock Vcore little high 1.63v not sure if want to run it at that for an long time, thats if its high i norm ran my cpu at 1.48v, does it even shorten the life of the cpu haveing it at that vcore setting 1.63v or as long as its been cooled well should be ok?

getting me 5600+ X2 {2.8ghz@ most likey get it to 3.1Ghz} to replace my sold 3800+ X2 {[email protected]} when i pick it up today

Kool, yea i thought its a little high aswell, ill have a play around again, prob get it lower when i get the 120.3 rad back on cooling the cpu reckon i mite get 3ghz out of it then

 

[Fireskull]

Nice clock!

But as said vcore is a bit high but if you have good cpu cooling then it's fine.

Also you maybe able to run x4 HTT multi to bring the HT link upto 1060Mhz. Increase the HTT voltage slightly if need to.

Gonna sound like a real noob but when i got taught to OC (from a friend ) he never actually explain anything really, is the HTT just changing the x11 to x4? but then obviously have to change the Bus speed?

Also got the voltage down to 1.552v any better?

 

[Fireskull]

Managed to get 2.97 with 1.552V but cant seem to get the magic 3Ghz to boot into windows

 

[Fireskull]

I think the x11 you were referring to is the CPU multi, Hyper Transport multiplier is a whole different thing that controls the speed of your HT link (between CPU & north bridge, similar to Intel's Quad-pump FSB). The default HTT multi is x5 which you have no doubt switch down to x3 when you overclock, generally the golden rule is not to let HT link speed exceeds 1Ghz but a decent mobo can usually do more than that - some mobo can even take HT speed of upto 1.5Ghz.

The HT link options maybe in the form of actual Mhz i.e. 200Mhz for x1, 400Mhz for x2, 600Mhz for x3...etc.

Oh ok ty for the info, i will have a look at that tonite, unless anyone reading has my mobo and knows what to change lol?

 

[Fireskull]

Need to also monitor temps. A high voltage equals high temps which in turn leads to instability & shortens the life of the CPU.

To find out quickly if the OC is good (stable, etc), you need to run a program to stress the main components. See here for more info.

Yea temps idle are under 40 which is only running on a single 120.1 rad with crappy pump, im gunna down the clock untill i can get it back on the nice pump and rad and ty for the link been meaning to download Prime95 and SuperPI

 

[Fireskull]

Found that HTT link, it was under K8 to NB frequency on my mobo and put that to 4, heres the result, that seem right? going to try Load testing programs now and if thats stable try for 3ghz stable again

 

[Fireskull]

Hope so, just probably got something not right somewhere, i can get 3ghz on bios but it wont even start the xp loading screen with 3ghz :/ also just tried some Prime95 and SuperPI and of the tests i did seemed ok and temps didnt go above 55 load even with only a 120.1 rad, but Orthos temps were almost 70C will get a faster fan on the rad and let that go tonite n see if its still stable
