Faulty CPU due to Heatsink misplacement

This CPU presented burn out evidence on the back of the PCB in corrispondance to the core, due to misplacement of heatsink.

Hi, I have an AMD 1800+ on a motherboard Asus A7V333. How much of a difference will I notice upgrading to this 2600+?? Can I use this cpu?

Response: On average it'll be about 20% faster, up to 40% faster in some applications (audio/video encoding).

Posted by: Robbie Vaughn

how would this processor compare to an intel p4 2.0 gig proc.with 512 L2 cache 400mhtz fsb.Would it make for a better machine.

Response: I think that Athlon XP 2800+ will be on average 20 - 25% faster than the Pentium 4 2 GHz/400/512.

How faster (in percents) Athlon XP 2800+ is, than Sempron 2800+?

Response: On average it'll be about 5% faster

Posted by: Keko-Computer

what i don`t understand is that a
Athlon XP 2700+ 333 FSB rolls on 2167MHz
but a Athlon XP 2800+ 333FSB rolls on 2083MHz
does it comes from the Cache memory

Response: The 2800+ can keep more program data/code in the L2 cache, and access to the cache is significantly faster than access to memory

thermal compund

Posted by: buddy

watch out on this one, like most Amds they run hot.
Mine didn't have enought thermal compund put onto it! NOT HAPPY, will be installing cpu myself from now..
lasted a good time considering i rarely turned off the computer.
pritty fast and worth it.
has a black burn mark on the back from where it heated up.
not sure if my bord is fryed or not.
just upgraded to a amd athlon 64 3200+ which runs as good if not better, as it was cheaper lol..

I have a AMD 2800+,it says it runs at 2000 MHZ.Wouldnt that be 2 GHZ?i can only get 1300MHZ and that is over clocking it.

Response: You're probably running it at 100 MHz FSB. You need to change FSB to 166 MHz.

These are great Barton cores and should be run at 200 FSB and yes they get hot, so use a good fan/heatsink and arctic silver or the like. a very thin smear remember you are making a direct contact not a sandwich

if the Athlon ex is 2800mhz it is
2.80ghz right??
corect me if i'm wrong...

Response: 2800+ is only the rating. Actual processor frequency is 2083 MHz.

AMD Numerics vs. Intel

2008-02-01 08:43:21
Posted by: Butch

The 2800+ does not represent true operating frequency.. It is a comparison relative to the Intel chips.. So, a 2800+ would operate as fast as an Intel 2.8GHz chip, even though it runs at a much lower frequency..

Came across this one on that auction site, AXDA2800DKV4E, not in your list is it genuine?

Response: Sorry, I don't know if it's genuine or not. I'll try to acquire one of these processors and test it.


2008-04-12 02:35:32
Posted by: snoobler

I purchased two of these from an eBay seller. The marking appeard completely genuine; however, neither processor worked in boards that would support "E" processors. I also tried them at lower speeds (100, 133 and 166), but nuttin...

I wonder if they were some chip particuar to an OEM?

Make sure you check things like your RAM (unbuffered, non-ECC, DDR400) and any jumper settings your mobo may have. I had to change my sticks to get mine to work.

Hi im looking for a processor that can run windows vista home premium 64 bit version, is the amd athlon xp 2800 Compatible with 64 bit software or can you reccomend any other socket A (462) processors that i can use?

Response: Socket A processors do not support 64-bit mode, so you cannot run 64-bit Vista OS on them.

Hey I was always told, but never believed it, that the last letter indicated buss speed. Such as c,d,e, would be 400, 333, 266. Looked right on the first few I saw in the same general speed range. Now I have to think about cooler weight. One thing about it it stays cool. Where is the best place to learn what is really going on. good luck

Clock speeds

2008-07-27 07:35:47
Posted by: Alex

It says its a 2800+, but it runs at 2.1Ghz, shouldn't it be 2.8?
I looked over the "interwebs" and found that the "projected speed" was 2.8ghz but the real speed was 2.09, WHY!!?!?

Response: 2800+ is the processor rating. According to AMD, the 2800+ rating means that this processor performs about the same as 2800 MHz

Performance boost

2008-09-08 11:29:42
Posted by: AJ

I have a server running a AXDA2500DKV4D. I'm wondering what kind of performance increase I'll get by switching to this one (I happen to have a used one laying around...)

Response: Performance boost would be very small (less than 10%), but if you already have one lying around then it makes sense to switch to

i was able to overclock my athlon xp 2800 from 2.09MHz, to 2.13MHz without pushing the FSB past 333..not a major difference, but i notice a slight speed increase on boot up.


2012-02-26 15:39:58
Posted by: cyanghost109

I'm surprised any of you all still are using this processor. I bought this years ago. Surprisingly, it runs COD4 and some other newer games.

@williamk7 overclocking the CPU won't decrease the boot time, it will only allow applications to perform more efficiently. But, this CPU is so old that overclocking it at this point wouldn't do any good (if running new programs).

@cyanghost109 problably just my imagination about the boot up speed increase..i am going to upgrade pretty soon to quadcore tech. as far as COD4 is concerned, thank god i have an xbox360. thanks for your advice cyanghost109..
