my pc recently died i thought it was time i had an upgrade
so i bought some new budget stuff the cpu is a athlon 7750 black edition (unlocked multiplier)

after a bit of playing i was having a fiddle in the bios as you do  and discoverd i can increase the clock speed  im currently on 17.5x multiplier
thats 3500mhz  from a 2.7ghz cpu using stock voltage. and cooled with a fanless cooler

has anyone else had any joy clocking an Amd cpu this far.

my understanding is that intel are kicking ass with their processors just now but for 60 quid i hought it was a bit of a bargain

With modern cpus, due to their better energy efficiency, any (unlocked) chip can be clocked pretty high when idle, without mega cooling.  Once the CPU gets busy, thats when you get the problem.

I once clocked my old Athlon XP-M 2600+ (1.8GHz core) to just over 3GHz...

ran fine for about 18 months till the evaporator on the phasecooler decided to leak, pished all over the graphics card and then went bang/pop/fire!

Ah, but the XP chip was truely awful, and marked AMDs downfall, chasing higher gaming benchmark performance, at expense of real world perfomance.

In all fairness though, for the price of the chip at the time, and the performance I actually got from it, I couldn't really complain!

Was it clocked to 3G clock, or clocked to same as XP 3000+

3G clock.  Highest temp it reached on load (running Doom3 for example) was about -2C.  Idle was down to about -38C

On the gaming PC got an AMD 9750 2.4 ghz x4 clocked to 3ghz with standard cooling and it's been running fine no extra cooling highest it hit in the summer was 45 degrees

i have to admit i went a little OTT withthe cpu cooler
i got one of these http://www.hardwarecanucks.com/forum/attachments/air-cooling/1861d1206891719-antec-900-thermalright-ultra-120-dsc05724.jpg

works good though

Nowt wrong with that.

What about some liquid nitrogen coolong.

im still thinking about submerging mine in mineral oil... what can be cooler? PC meets fish tank

I've done also overclocking on many cpu's..

Cpu's alone can be overclocked due to their production quality but problem is other related hardware can not keep with that performnce increase on the long term..

ram modules,chipsets,graphic hardware and disk subsystems also must be capable of answering that speed increase..otherwise only core cpu speed increase only effects the performance depending the the nature of running code..if its I/O dependant gains wont worth the reduced stability of total system..

so my personal view is that : most of the overclocking adventures result with reduced stability of systems crashing or freezing frequently..At least on the long term.. :-/

Reduces component life as well.

[Del Boy]

Thinking about maybe brining it back to stock as, as TB says reduces compnent life also there is only a little difference anyway.

[TheBoy]

For most overclockers, the life is unimportant, as these kind of enthusiasts only keep their machines a few months....
