This is an error in CPU-Z. CPUID of 40FF2h is DH core what is single-core with 512 kB L2 cache. No way it can be a dual-core with disabled core as core BH has CPUID of 40FB2h and core JH has 40F32h.
No idea. But I don't think TCaseMax value depends on batch number. It's more likely it depends on quality of silicon used and therefore the chips manufactured on the same week may perform equally.
As expected this is JH-E6 chip (dual-core with disabled core), not a classic SH8 single core.
Right. They can lower multi.
They are all SH8-E4 cores. "San Diego" and "Venus" are not names of the cores but of processors!
I think it is a dual-core chip with one core disabled (therefore a single core with huge die size). It's likely because of the revision - all 1MB dual-cores are E6 while all 512kB dual-cores are E4,...
I know the later variant is more probable. But still it is strange why 30xxx when the change is not that big, just a disabled dual-core.
CPUID 30F72 ? That is very strange! All C revisions have 00xxx, D revisions have 10xxx and E revisions have 20xxx. Is this 65nm processor? And if it is not, then it might be a dual-core with one core...
Read this . You will find benchmarks of Sempron s754 w/ 128kB, Sempron s754 w/ 256kB, Athlon 64 s939 w/ 512kB and Opteron s939 w/ 1MB. All on the same frequency.
4279 includes VAT while 3596 doesn't. Try to contact Mr. Blaska or Mr. Hlousek to see if they can ship it to Hungary. Contacts
See the RAMs I used - here
You better read the review. Opteron s939 can use ECC as well as non-ECC unbuffered memory.
Venus vs. San Diego - the problem is this mess in names. There is nothing like San Diego core. Cores are...
Opterons for s939 use unbuffered non-ECC or unbuffered w/ ECC. They can not use registered DIMMs. The memory controller is exactly the same as on A64, therefore with four double sided DIMMs, you have...
They are available for sale in our country - here .
Opteron 144 can be bought for a price comparable to A64 3000+. According to AMD's pricelist, it's even cheaper than that!
There is no difference between Opteron and San Diego A64. Both use the...
They are also shipping for s940. s939 versions were launched only a month ago so currently they are hard to get.
Not sure but Opteron is manufactured on better silicon because it is a server product and has higher demands on stability. It also usually has higher TCaseMax specification than Athlons.
Because it doesn't need registered memory, therefore the platform is much cheaper.
Yes, they do work on normal motherboards as Hammer Unknown Model. Some motherboards have a direct support for them - for example Abit AN8, ASUS A8N or DFI. I think more are to come.
At this speed...
Hi!
I published the first review of a new Opteron socket 939. This CPU uses San Diego core SH8-E4 and features 1 MB of L2 cache. It is available at speeds 144 (1.8 GHz) to 154 (2.8 GHz). Price...
All A64s are capable of supporting ECC.
This seems to me like there is a connection between TCaseMax and overclockability. Those of you having above 60 degrees also run at higher frequencies than average.
For new posts - could you also...
This is a maximum temperature of CPU's case, that is a temperature on it's Heat Spreader (nothing to do with case, power supply, HDDs ect.). It is specified as absolute maximum rating. AMD say the...
Not possible from heat spreader but CPUMSR will tell you when you are in Windows.
