OCZ Blade PC3-16000 CAS 7 6GB Memory Kit - Test System Setup and wPrime

We look at a low latency set of PC3-16000 modules from OCZ today and find out if they're able to impress as a top end choice for your i7 rig.

Test System Setup

 

Processor(s): Intel i7 920 @ 4GHz (200MHz x 20)

 

Cooling: Noctua NH-U12P (Supplied by Noctua)

 

Motherboard(s): GIGABYTE EX58-UD5 (Supplied by GIGABYTE)

 

Graphics Card(s): ASUS GTX 285 (Supplied by ASUS)

 

Hard Disk(s): Western Digital 300GB Velicorapter (Supplied by Western Digital)

 

Operating System: Windows Vista SP1 64-Bit

 

Drivers: ForceWare 185.65

 

What we'll be doing is having a look at how this kit runs against the A-DATA one we looked at the other day which uses similar timings at 1600MHz, but also managed to run at 2000MHz with more relaxed timings.

 

We'll find out if the extra aggressive timings OCZ offer us gives us some more performance which is pretty much what you want out of an expensive 2000MHz kit.

wPrime uses a recursive call of Newton's method for estimating functions, with f(x)=x2-k, where k is the number we're sqrting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum.

In our first test we can see that at 2000MHz both modules perform quite similarly. The OCZ modules do come in slightly lower, but not by a huge amount.
