hi there
i just put together my backup comp sk41g,now i know they wont break any overclocking barriers but ive read that they do go a little way to providing a few more mhz,
this is the first time ive ever tried this so i have no clue realy on what to do or absolutely anythin about voltages,,whats more is that the xp1800 i have in there i dont think it is of any special calibre to give me very much in the way of overclocking,also im curious as to why its operating at 1.76v while my xp2400 operates at 1.60v,would i be wrong in assuming that 1.76v seems slighly high compared to my 1.60v xp2400,or are there xp1800,s that have to operate at this voltage?
they both run idle at around the same temperature of 44-46c and i read somewhere that the higher the voltage = more heat hence higher temps,is it possible to reduce the voltage on the 1800 to see how much it would actually knock off temps or is this its optimum operating voltage?
sorry i have no stepping code or anything for the processor so im realy not to confident ile be able to do much with it,but any info would help greatly on overclocking and voltage of 1800,s,the system is pretty much standard at the min :
athlon xp1800 (1.53ghz)
512mb pc2100 ddr
60gb hardrive
nec dvd/r
using onboard graffics at the min
will i need to update my bios to overclock or will it be fine as it is?

Your XP1800+ is most likely a Pally, LOCKED (no mult adj so bad for FSB increases) and VERY hot. Sell it on (I'll buy it) and get a £40 TbredB XP1700+ (ensure TbredB) or £70 Barton XP2500+. Both of these can run around 2.0ghz (speed of XP2400+ & XP2700+ for Barton) with only 1.50-1.55v! They should happily run 400FSB if your mobo and RAM allow too, always unlocked so full mult adjustment. If you don't mind a little more heat then at 1.65v you should find 2.2ghz easily possible making the TbredB an unofficial XP3000+ and the Barton an official XP3200+. Seriously, sell your current CPU and buy one of the above. Your mobo supports voltage and multiplier adjustments right?
If you're o/c'ing to boost games forget it. Onboard gfx are GF4MX (enhanced GF2) at best and a comparable seperate AGP card is only £30. If you want a gaming boost look to a GF4TI4200-8X 128MB for £75 at 

Again depends a lot on the CPU. TbredB lower than XP2000+ often use 1.50v and it's still std voltage to use 1.65v, 1.75v is as high (or higher) than I'd advise to go. Barton tend to all use 1.65v but if you have a Barton (or TbredB) running <= 2.0ghz you should find 1.55v VERY stable and VERY cool! Again 1.70-1.75 is tops IMHO.
I think that depends on the particular Shuttle. An XP-TMC Skt adapter is probably best allowing use of TbredB & Bartons on unsupported mobos and full range of multiplier and voltage (IIRC) options.
IMHO yes definitely do put that 4200 in your sk41g, maybe game or bench it then see if you notice the perf diff (LOL). If you want more then sell that XP1800+ Pally, put your XP2400+ in sk41g and then buy the XP2500+ for your sn41g2 (with some PC3200 RAM to allow 400FSB). Yummy!
