AMD 2800 XP, Barton or thoroughbred

[jotto]

Have been looking at prices of the xp2800 and have been quoted same price for barton and thoroughbred. It looked as though the clock speed of the barton was actually slower. Can some one tell me the difference and performance wise which is the best option.

[Imperion1]

Thoroughbred: 256k L2 cache, 333mhz bus

Barton: 512k L2 cache, 333mhz bus (Barton 3200+ and newer is a 400mhz bus)

[Bigjakkstaffa]

Yeah the barton is clocked slower due to its higher FSB and L2 (although it dont make a really big difference) brings it up to the 2800+ PR speed. If your mobo supports it i would go for the barton as i dont think either of these chips are great oc/'ers and i aint read much to disprove that statment.

get the thoroughbred if overclocking, barton if not.


with stock settings, the tbred dont oclock that well, but i read sumwhere that cutting/joinig bridges to make its default fsb 133 instead of 166 makes it more overclockable

(gives it more headroom - more overclockable for some reason - may work on the new barton as well--turn that 200fsb bad*** into a great overclocker!!)


i repeat: get the thoroughbred if overclocking, barton if not.

but i read sumwhere that cutting/joinig bridges to make its default fsb 133 instead of 166 makes it more overclockable

Just out of interest why would that work better as opposed to say just setting it to 166FSB in softmenu?

BTW if your new to the world of computers or a beginner i wouldnt advise you to go cutting bridges at all, if you must, do some very very thorough reseach at least

i dunno, but a chip with default fsb of 166 will not clock as high as if u set the default down to 133 by cuttin/ joinig bridges


it was discovered by a guy who did it in reverse - he set his 1700 to default fsb of 166 (on the chip, not in bios). he noticed he couldnt geet it as high as before. he put it on some forums, some people with bartons tried lowering default, their bartons suddenly became as good at overclocking as tbreds

noone knows WHY it works, it just does.:D


...and jakk, fix ur sig :t

Get the 2500 Barton, can get to 2800 easily - haven't heard of one that didn't, most can do it under the stock heatsink. I've gotten mine up to 3200+ cool and stable on a ****ty volcano aircooler which I only lapped.

[Bigjakkstaffa]

I've gotten mine up to 3200+

Yeah there was a story on hardocp about a guy who has had his last seven XP2500+'s runnign at 3200+ straight out of the box, no fuss... nice

--Jakk:t

[Someone Stupid]

especially considering that a board which does it is 90-100 dollars and the chip is around 100.

[bert202]

Memory is more important than the clock speed. The processor usualy finds the info it needs in the catch 90% or the time so the bigger the catch the better. The L2 catch goes much faster than ram so the more it finds in the catch the better.

Another vote for the now very cheap Barton 2500 (£62 here in the uk). Mine clocks to 2400MHz (12x200FSB) on ASUS A7N8X DLX REV 1.04 BIOS 1004.
BIOS 1004 on this board has a selection for 200FSB and works great. That's a higher clock speed than a 'new' Barton 3200+ 200FSB for about 1/6th the cost :)
Temp only went up to 46C when clocked which is very acceptable.

Terminator, where can you get on eof these for 62 quid? cheapest ive seen is 75 not including vat.

[Terminator]

Hi Dan2003

http://www.overclockers.co.uk/acatalog/Online_Catalogue_AMD_CPUs_51.html

link to www.overclockers.co.uk they have them for £62 + vat+del
Recommend them because it's where I got mine and clocks very well.

Thing to watch out for with ocuk is their really expensive shipping usually puts a tenner extra on the price, then VAT, then the fact their tech support is virtually non-existent... they used to be so good too :(

Well if no happy with overclockers then try link below :-
http://www.ebuyer.com/customer/products/index.html?action=c2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=46513

Retail version from www.ebuyer.co.uk for the same price. Bought thousands of pounds of gear from them and never had a problem with support/RMA etc.

PS. You might want to look at www.eclipse-computers.com as they have 2500XP's at £58.95 but their crappy web site doesn't say wether it's a barton core but I don't think T-Breds came in 2500 ???? or did they.... could always call em. Please note I have never ordered anything from them.

PPS. Shipping from overclockers is £3.48

[Bigjakkstaffa]

The only 2500+ is indeed a barton, as for ebuyer, where ocuk's tech support is virtually non-existent, ebuyers IS non-existent, if you put a request thorough to tech your talking months rather than days for a response.

Best place ive found for price to support ratio is scan.co.uk, only problem is the courier they use is utter **** :rolleyes:

GAD! Can we not have a service that does it all right for a change :x

--Jakk:t

oh and btw last time i bought from ocuk going rate for shipping was 9 quid at a time

[dan2003]

oh yeah, didnt think to look on overclockers!
