3400+ Clawhammer detected as 3200+

I have a DFI Lanparty UT nF3 250Gb with a 3400+ Clawhammer. For some reason I'm only running at 2.0GHz...

CPU-Z detects it as a 3200+ Clawhammer, with core speed of 2000 MHz and 10X multiplier with HTT at 200 MHz. This is when I have everything set on "Auto" in the BIOS (except FSB which is at 200 MHz). The problem is that when I set the CPU/FSB multiplier to 12X in the BIOS and boot up, nothing changes (CPU-Z shows the same settings as above).

Am I missing something? Should I be messing around with the LDT settings?

Thanks for any help.. I've never messed around with A64s before.

EDIT: Oops I shouldn't have been trying 12X at all. But I'm now trying 11X and it still only shows the processor at 2000 MHz.

EDIT 2: First one to solve my problem and get this POS running at 2.2GHz with 200MHz FSB and detected as a 3400+ gets $1 via PayPal. 🙂

I have a 3400 clawhamer as well.

You CAN NOT RAISE the multiplier on A64 processors, with the exception of the FX series. The maximum fsb/cpu multiplier for that chip is 11x, this multiplier can be lowered but not raised. Try booting the CPU up at a 11x multiplier and get back to me.

Ok I set the multiplier to 11X in the BIOS, however CPU-Z still says i'm at 10X and 2GHz. I noticed something in the BIOS saying something called "Clock Spread Spectrum" was disabled if that means anything to anyone.

bjc - I don't have the stepping, where can I find that?
 
Is it possible that this processor is in fact a 3200+? I didn't think that was the case because the number on the front of the CPU had a "3400" in it, but that's all I can think of.

I just increased the FSB to 210 and am now running at 2100 MHz, so it's not a BIOS or CPU-Z reporting error. It seems that it won't allow me to go above 10X multiplier in the BIOS.

Ideas?
 
That happened to me too with my 3.2 Prescott. Kept on thinkin it was 2.8. Got sum new Bios up in that piece, and boom, prob solved.
 
Have you contacted tech support at the place you got the processor from as well as AMD? Are you sure the markings on the chip said it was a 3400+? Maybe CPU-Z is reporting wrongly. Here's what you should do to double-check:

- Get and run AMD CPUInfo and AMD CPUID from http://www.amd.com/us-en/Processors/Tec...alResources/0,,30_182_871_9706,00.html
- Search google for CPU-Z 1.28.6, for some reason this newer version is not on the official CPU-Z site. See if it returns the same result as the previous version. Maybe the proc you have is a newer stepping, how long ago did you get it?

Also reset the bios, and if the mobo is old it *might* help to flash to a newer version. I'd do that only after contacting the mobo maker's tech support though.
 
Hehe I didn't see the $1 paypal offer 🙂 I just hope you get your problem resolved, it stinks when your hardware does not perform to spec, much less identify as less than spec. Running the AMD cpu id utilities should confirm what the processor is. If it confirms as 3400+ then maybe you've got a wrong bios. Anyway do contact the chip retailer and explain the problem. PM me if you are successful!
 
Ok, I'm back. I reset the CMOS, didn't help. No help with the latest BIOS either (5/4/2005 as bpm3k said).

Now, I downloaded all the mentioned tools, and when I ran Central Brain Identifier I saw under the "Tweaks" section where you could change the CPU String and I just remembered something:
When I first put together my system (earlier today) and started it up, I ran CPU-Z and it gave the Name as "AMD Athlon 64 3200+", but the Specification was "AMD Athlon(tm) 64 Processor 3400+". After this is when I started messing around with the BIOS settings, and ever since CPU-Z has shown both the Name as "AMD Athlon 64 3200+" and Specification as "AMD Athlon(tm) 64 Processor 3200+".

Now, I just did the tweak from Central Brain Identifier and updated the CPU String to "AMD Athlon(tm) 64 Processor 3400+", and now CPU-Z shows exactly what I saw when I first started the system up (Name as 3200+, Spec as 3400+).

Does this have anything to do with anything? Could this in fact be a 3200+ processor that someone renamed to a 3400+? I did buy it used after all (from FS/FT). The thing is.. I am positive the number on the CPU heatspreader had a "3400" in it.

AAAHHHH!!!!!!!!1

EDIT: speling
 
Did you use AMD's official cpu id utilities? I think for id'ing the processor (not clocks and such) the best bet is the official utilities. CPU-Z can and does have errors. It incorrectly identified my new A64 3500+ as Newcastle core even though it is a Clawhammer. The newer version of CPU-Z 1.28.6 correctly identified it as Clawhammer. Anyway do run the AMD utils if you haven't yet.
 
Uzair: Yup I've run all the AMD utils mentioned above.. CPU-Z, AMD CPUInfo, AMD CPUID, and Central Brain Identifier. They all say 3200+ (until I changed the CPU String as mentioned in my previous post).

Regarding the member who sold it to me, I'd rather not say because I don't want to jump to conclusions yet.. he has good heat and has been an active trader. I'll wait for him to reply to the PM I sent.
 
Well then that is serious. If it is not too much trouble can you remove the heatsink and look at the detailed markings on the heatspreader? If you do write them down for future reference. If the markings are 3400 then that would be weird cause it should not be so easy for a person to change them. Another thing you should do is match the serial number on the processor with the number on the box. Apart from this I can't think of much else to be done other than talking to the guy you got it from. Ask him where he got it from in the first place.

I sincerely hope your problem is resolved!

Spell: write is not spelled "right". Doh.
 
I dont know if this is the answer to your problem or not, but here is a guess...

AMD's early number rating system is ambiguous. (no im not knocking amd, I love them also)... but
For nearly every rating....There were 2 amd cpus with the same rating. Here is the difference...
The standard model is a cpu with a X.Y Mhz rating with 512 L2 cache.
The is also a model with X.(Y-2) Mhz with 1MB L2 cache.
Both of them were rated at the same zz00+ speed bin.

So, possibly your 3400+ could be...
a 2.2Mhz cpu + 512L2 cache or...
a 2.0Mhz cpu + 1MB L2 cache.
 
Hey yeah, good one sao. Why didn't I think of that? That could be a very obvious reason. sundevb what does CPU-Z say about the amount of L2 cache? If it is 1MB then it could be a 2.0 GHz 3400+ with 1MB L2. But in that case AMD cpu id would not make mistakes. The best bet is to take off the heatsink and check the designation there.

Keep your CPU at 11X

Just take the FSB off Auto and set it to 206 and you will bet at 2.2

Technically you would be OCing your board a tad but not the CPU.
 
You guys, the clawhammer 3400+ should run at 2.2, as the newcastle (512k of L2) runs at 2.4. If you can't set your mulitplier to 11x, either your board is borked or the processor isn't a 3400+, case closed.

But... the Clawhammer 3400+ is supposed to run at 2.2GHz with 1MB L2 cache (1MB L2 is what is reported in all the above programs). Since I paid for a Clawhammer, it should run at 2.2GHz at stock speeds.

Uzair: I will take off the heatsink soon, and let you know.
 
he cant set the multi to 11x. that cache size thing is the same with venice vs. SD the SD's are 200mhz slower, but have a bigger L2.

Umm, yeah, and? A stock S754 3400+ with 1MB cache is 2.2 GHz last I looked... that's 11x200. So explain again why he shouldn't be able to set the multi to 11x?

S754 3400+ 512k cache are indeed 200 MHz faster, at 2.4GHz, not that that has any relevance to the OP.
 
have you read any of this thread? the problem is his 3400+ is acting like a 3200+. the 11x multi doesnt work, and cpu z detects it as a 3200.
