<font color=blue>Hi there
AS most people are aware, Sisoft Sandra benchmarks can easily be faked by the use of CS speed cheats. Which is really sad, and it really annoys the genuine overclockers, who spend a lot of dosh on their kit and spend hours tweaking, to have all of their respect taken away by some blagger who thinks it is good to go and cheat.
Well I myself and OcUK regular Mulda have come up with what we to believe a way to work out if the posted Sisoft Sandra benchmarks are fake or legit, by using a simple formulation, which I shall explain in a minute.
I had the genuine CPU speed to do comparisons against faked claims, and Mulda came up with an easy formulation. I am able to clock my 1.4Ghz CPU so high because it is running at -5c, as I am lucky enough to own a Vapochill case and enjoy high overclocks in silence.
Obviously requesting a 3D Mark 2001 FULL Test and maybe the OcUK or Teamlambchop SETI Benchmarks would also prove their claims, and give them the respect they deserve, as I believe neither of these two tests can be faked, and I hope I am right.
Anyway if they still deny your request and only insist on posting WCPUID shots or Sandra benches that could easily be modifed or done with a speed cheat then use the following formulation, so to suss if they are telling the truth or if they are liers.

For everyon else's benefit, for any one particular CPU type (e.g. TBird) then the CPU and CPU Multimedia benchmarks are a measure of pure processor power/speed and scale linearly with clock speed irrespective of FSB. So, 50% increase in core clock speed will give 50% increase in Sandra for these.
Obviously there will always be a spot of 'experimental error' as no 2 runs give exactly the same result, but it can be used as a general guide.
So, the easy way to do this for someone's posted results is divide their score by the score for a 1.0 CPU (in this case TBird) given by Sandra...
To take his ALU Dhrystone score from the CPU bench:
4862/2805 = 1.733
So, ******* claim:
CPU Benchmark
ALU = 4862 Dhrystones ~1.733GHz
FPU = 2763 Whetstones ~2.009GHz
CPU Multimedia Benchmark
Integer MMX Enh = 9648 it/s ~1.766GHz
Floating Point 3DNow! = 11171 it/s ~1.633GHz
Gibbo's reality:
CPU Benchmark
ALU = 5092 Dhrystones ~1.815GHz
FPU = 2516 Whetstones ~1.829GHz
Hope this helps everyone

Here is a Sisoft Sandra CPU benchmark of my system at 1826Mhz (11*166):-
As you can see my system scores a legit 5095 Dhrystone ALU MIPS and 2516 Whetstone MFLOPS.
Use Mulda's formula which is the suspected person's ALU and FPU divided by the reference AMD Athlon 1Ghz ALU and FPU values.
The Reference 1Ghz Athlon scores 2805 Dhrystone MIPS and 1375 Whetstone MFLOPS.
So you would divide suspected result by the reference results ALU scores and then the same for the FPU scores.
Me (Gibbo) Legit 1826Mhz CPU Bench
5094 / 2805 = 1.816 (1816Mhz)
2516 / 1375 = 1.830 (1830Mhz)
Un-named character who claims to be running at 1826Mhz (11*166) out of a 1Ghz CPU air cooled
He scores 4862 Dhrystone ALU MIPS and 2763 Whetstone MFLOPS.
This person has been asked to submit 3D Mark 2001 FULL TEST, and/do the SETI Benchmark, but he wishes not to comply and gives lame accuses.
All he has is a low quality screen grab of his desktop with WCPUID and Sisoft Sandra scores. Which due to picture editing and speed cheats is not really proof these days.
However lets check out his Sisoft Sandra CPU bench using our formula:-
4862 / 2805 = 1.733 (1733Mhz)
2763 / 1375 = 2.009 (2009Mhz)
So as you can see for a claimed 1826Mhz benchmark it quite clearly is not, and has obviously been CD speed cheated.
The same method can be used on the Multimedia Sisoft benchmark too, if the score is legit that after using the formula you should get a result that is close to their claimed speed. If the score is fake, your results will be quite far out after using the formula and they will also be inconsistent.
I think myself and Mulda deserve a round of applause for this one, as hopefully we'll put an end to people posting fake benchmarks.

These two guys do indeed deserve a round of applause.
Please post what you think and whether it makes sense.
