Upgrading and overclocking (htt) Dell C521 with 3600x2.

[eizoer]

I have just read the quick and dirty post and find myself a bit bewildered.

According to a review in the UK version of Custom PC, without overvolting or adjusting anything else then changing the htt from 200 to 266 the chip would run just over 2.5GHz with the temperature only increasing 3C under load.

Is this right?

I just bought half a C521 (including cpu) and built it up again and was hoping the review would mean i would have a 5200x2 system for free.

I am planning to eventually install a sff (if there ever is one) ati x2600pro and a hddvd/ blu-ray combo drive and keep it in the living room.

Anyone tried anything like this with this system (nforce 6250le motherboard) ?

Cheers.

From what I have heard those 3600+ overclock great with the right motherboard, I have heard of them hitting upper 2ghz-ghz speeds. First does your bios support overclocking since you said you bought half a dell machine if the board is dell it might not support overclocking. are you sure it is a nforce 6250 le because that sounds like maybe that is the integrated graphics. Also don't get your hopes up because all chips overclock differently and all motherboards overclock differently. I probably could overclock my 5600+ a bit more and saved if I had paid an extra $250 for better ram and motherboard.

PS post the ram and rest of the system so people can get an idea of what they need to overclock

The dell doesn't have any overclocking options (greyed out) but i found a post (search for woooot) which finished a month ago where they were using cbid to overclock the cpu without changing the htt but apparently the program can change the htt but i don't know if they are talking about the same thing as the magazine.

The article read "Even without overvolting the X2 3600+, from its default core of 1.35v, we managed to push the HTT speed to 266MHz, producing a core speed of just a smidgen over 2.5GHz. This puts it between Athlon 64 X2 4800+ and 5200+ clock speeds (somewhere between a £79 and £100 cpu). As we didn't push any more current through the silicon, the X2 3600+ maintained its cool poise, never exceeding 48C. At this speed, it scored 1.49 overall, which isn't a bad score at all, especially for a chip that costs £45.".

The motherboard is a nforce 430 (nforce 4 or 5?) with 6250LE integrated graphics, though i have a x300 sff card installed untill i upgrade the ram from 512mb.

I was assuming the chip was actually a 1066 (266) MHz AM2+ X2 5000+, underclocked. That increasing the HTT would restore it without worrying about any other settings or the chip overheating (the dell is a btx case with just the cpu/ psu fans and no space to install another).

Since its the same system here and in the US and their first amd cpu i was hoping a lot of people had already tried something similar and could detail a safe way of trying it myself.
