IQYHA 2600 Mobile Athlon XP

[Solus]

Okay, my mate recently gave me this as he just upgraded his rig (I run 2 rigs atm). My 2nd rig is currently running an ASRock K7-Upgrade 880 with a Sempron 2200+ @ 200x9 = 1800mhz. 2xDDR333 512 in dual channel.

I'm going to have a little play about with this 2600+ (IQYHA) in this rig. Do you think I should go for a 166fsb due to running in sync with the ram?

Also, can I change the multiplier via jumper? (I've heard you can't but just checking).

I'm hoping to get something around the 166x14 mark to make around 2.3ghz, what do you guys think?

Hey and thanks for your reply.

The board does support 200fsb, but doesn't have PCI/AGP locks, so basically the max I could probably go is about 215.

I could perhaps run it like this, with my ram async at 133/333? But would this reduce performance compared to a lower FSB, higher multiplier and sync'd memory and cpu?

Also I do have multiplier settings I can set on the motherboard using jumpers (not via bios) but I have heard that this doesn't make any difference to the multiplier it uses as it is a mobile processor, so it always uses a multiplier of 6? I'd like to know if this is true before I try it out.

Obviously the only way I could get around this then would to boot at the lower clock speed then alter it using CPU Crystal ID in Windows.

EDIT: Just to make it clear what I'm asking here, as I did cover a bit of all aspects. Which would be faster? For example: 166fsb, 14 multiplier and Memory in dual channel in sync with cpu or 200fsb, 11.5 multiplier and memory not in sync with cpu bus speed (running at 166).

That link states Dual Channel, and it definitely says running in dual channel in CPU-Z.

Anyway, thanks for the advice. I think I'll try memory and processor at 166fsb, and multiplier at 14 to start out. I can't try it tonight as I need some thermal compound (i'm all out atm ).

I'll let you guys know how it goes, again thanks for all response and help.

I can actually set the FSB via jumper on my board, and it works fine (it's how I overclocked my sempy above). And the PCI/AGP buses seem to be at stock (33/66), so i'm pretty glad the jumpers on my board solve that problem.

Or have you told me this in order to benefit me in another way? It's just the multiplier I can't set without a program in Windows.

Hey all, just thought I'd get back to you to say my first attempt is doing fine.

I know the temp seems a bit high in that print screen, I took the case apart again and noticed a lot of dust under the fan, on top of the heatsink. So I cleared this off and I now idle at 45c rather than 47c. I know it's not a big difference, but this seems fine for a mobile processor though?

I know they have some sort of higher max temp compared to desktops.

EDIT: I have now placed the multiplier at 15x to give a speed of 2.5ghz, everything's prime stable etc. Temps are 50c Idle, 54c Load. Are these temps okay considering it's a mobile CPU?

Bump,

at 15x166 I got a blue screen while priming. Could this be the limit of the processor? It can't be heat related as it simply doesn't go any higher between a multi of 14 and 15.

Hi, the reason I am running @ 166 is so the cpu and memory are in sync with another. As I have 1 stick of DDR333 and 1 stick of DDR400 in this system.

If putting the processor at 200fsb and the ram in async at 166 would this result in a performance decrease rather than 166x14?

I did try this previously with the old Sempron, and I used to get a blue screen now and again. I suppose I could try to slacken the timings, but i'm hesitant to put more VDimm through it, as obviously I can't monitor the temperature of my ram sticks.
