AMD X2 3800+

Gashman · 30 Mar 2007 at 17:01

does anyone know if 3800+ revision BH-E4 are good overclockers? know someone who just bought one and hes wondering how fast he can get it, on asus A8N board

steve258 · 30 Mar 2007 at 17:03

You should be looking at the stepping info printed on the IHS.

The revision BH-E4 simply means the chip is a Manchester core whereas revision BH-E6 is a Toledo one I think.

well thats a problem, since he lapped it :eek:

anywhere else one can obtain the stepping?

jaykay · 30 Mar 2007 at 17:28

sadly no the ihs is the only way of knowing what steeping it is

steve258 · 30 Mar 2007 at 17:29

No better way to find out then actually overclocking it me think.

CPU-Z??? btw i have a 3800+ with the manchester core and i can say that it doesnt wont to post past 220Mhz

steve258 · 30 Mar 2007 at 18:13

The stepping number in CPU-Z refers to something else. What you should be looking for is the codes on the IHS like LDBFE 0622WPMW.

Every Manchester core X2 is different, with the best ones capable of 2.7-2.8Ghz (ones ending in XPMW if I remembered it right).

I remember using something like CPU-Z to get better information on an unknown CPU I had, think it was called something like Central Brain Identifier, I'm sure it had the stepping in the table.
Should give it a go, it was a pretty decent tool, better than CPU for what I needed.

steve258 · 30 Mar 2007 at 19:45

Just checked the central brain identifier and it doesn't show the stepping code I'm afraid

Emlyn_Dewar · 30 Mar 2007 at 20:03

Sure it's the same program? Just found the screenshots I had for the site and it has the stepping on the main result page. Seemed to be the same for all of them, unless it doesn't work with X2 processors... Which could be possible.

Toledo's are only good for 2.8ghz stable whereas Manchester cores should reach 3ghz stable.

Defcon5 · 30 Mar 2007 at 23:46

Ive got a manchester, it will do 2.8 @1.45v (currently running this - bad temps

)

It will do over 3ghz with phase, at 1.8v though, not ideal for 24/7!

Gashman · 31 Mar 2007 at 00:41

does this mean anything? ADA3800DAA5BV

Edit: forget that, thats just his model number i think, well the maximum overclock he has got so far is 2.5Ghz with no real tinkering with memory timings or anything, he has mushkin extreme performance 3200 (the black stuff) running at CPU/12 ratio, all he done is upped his voltage to 1.4V and dropped HT multiplier to 4x, gonna see if we can get 2.75 tomorrow, his cooler is CNPS9500 by the way

what motherboard do you have? has anyone heard of the A8N-SLI being iffy when it comes to overclocking, cause mine behaves in a bizarre manor, the second i try 250Mhz it crashes and says boot failed due to overclocking, how high do these boards go cause i have apogee waterblock so temperatures aren't issue, but i just got round to cooling the chipset and voltage regulators (just above CPU socket), will that help overclocking cause the A8N is passive cooled usually

Yep the same program mine is 8.1 and the stepping number in there is the same shown in cpu-a, not actually the stepping code you find on the IHS.

Last time I heard Toledos are used in high-end X2s and FX chips and are capable of higher clocks. All the golden steppings CCB1E / CCBBE...etc are all Toledo cores.

Cyber-Mav · 31 Mar 2007 at 13:12

my opteron is a toledo. so i guess all opterons or most of them will be toledo cores.

I see but that only applies to X2 3800+ though - there are far more manchester 3800+ than toledo ones, let alone a good stepping toledo.

Its a DFI Ultra-D, modded to SLi, with 704-BTA bios

Lower your CPU multi, and put the ram divider to its lowest, along with the HTT bus, then as you raise the FSB the only thing thats being strained is your mobo. Try a different bios too

my toledo 3800 x2 lcbie does 2.8 ghz on stock vcore and 3ghz on 1.55v folding@home stable, have recently clocked it down to 2.7 though due to high temps.
