Test Setup
To ensure that all reviews on Overclock3D are fair, consistent and unbiased, a standard set of hardware and software is used whenever possible during the comparative testing of two or more products. The configuration used in this review can be seen below:
OCZ ReaperX (PC2-6400) 4GB | Mushkin HP2-6400 (PC2-6400) 4GB | |
| Processor | Intel Core 2 Quad Q6600 "G0" 2.4GHz 2x4MB | |
| Motherboard | DFI Lanparty P35-T2R | |
| Graphics Card | Sapphire Ultimate X1950 Pro 256mb PCI-E | |
| Hard Disk | Hitachi Deskstar 80GB 7K80 SATA2 7200RPM 8mb | |
| CPU Cooling | Stock Intel Aluminium Cooler | |
| Operating System | Microsoft Windows Vista Ultimate (Latest Updates) | |
| Graphics Drivers | ATI Catalyst 7.4.44981 | |
| Motherboard Drivers | Intel INF 8.300.1013 | |

Settings & Overclocking
As with all memory reviews on Overclock3D the ReaperX PC2-6400 modules were subjected to a series of benchmark tests under several different configurations. The configurations used tested the memory's ability to run at high frequencies with stock timings, high frequencies with loosened timings and also ensured that that the modules could run with 100% stability at their advertised speed, latency and voltage settings.
Stock Frequency & Timings
DDR2-800 / 4-4-3-15 / 2.1v
DDR2-800 / 4-4-3-15 / 2.1v
We've already mentioned that OCZ only guarantee the ReaperX PC2-6400 kit to run at its advertised 4-4-3-15 timings on an Nvidia 680i based motherboard with EPP. This certainly seemed to be the case when we first placed the modules in our Intel P35 based DFI Lanparty board, attempted to boot into Windows and was welcomed by repeated BSOD's. No matter what settings we tried, we just couldn't get the modules stable.
However, a quick browse of the OCZ website revealed a link to their forums where there was extensive information and a guide on how to get the ReaperX kit running stable on a range of Intel P35 based boards. After changing the settings on our DFI P35-T3R to the ones suggested on the forum, the test PC booted into Windows flawlessly and passed several hours of Prime95 stability testing.
Highest Frequency @ Relaxed Timings
DDR2-1098 / 5-5-4-18 / 2.1v
DDR2-1098 / 5-5-4-18 / 2.1v
Overclocking the ReaperX on it's stock timings of 4-4-3-15 was't really much of a success on our Intel P35 based testing platform. This certainly didn't come as a surprise, as the modules are only really designed to run at CAS4 on Nvidia based chipsets. However, on loosening the timings to 5-5-4-18 the ReaperX kit showed us exactly what it was capable of by coming just shy of DDR2-1100. This is extremely good for a 4GB kit, and as we can see from the graph below; the Mushkin kit also used in this review couldn't even come close.
Now that we've got the overclocking out of the way, let's see how the ReaperX sized up against the Mushkin kit in our benchmarks over on the next page...

Quality review mate..
They just look so damn good and preform just as well.. 1100mhz!!
Is it just me or does the percentage at the end not show up??
Oh yeah one more thing... On the 3rd page when saying about what OCZ say the stock timings are on the RAM you say they are 4-4-3-12 when I think they are 4-4-3-15.. Correct me if I'm talking out of my arse though

I bought these, boshed em in...no tweaking at all and straight to 990MHz. Not had time to fiddle but as you can see there's plenty of headroom

Nice Review , is this the same kit as the one from the xmas comp?
, is this the same kit as the one from the xmas comp?Jimbo,
My bank manager wants a word with you. He said, 'Mr. Smith, why are you spending money like it is going out of fashion?' I replied 'It's Jim's fault'... I gave him your number...
My ram arrives Friday!

Deffo check out that thread on OCZ forums btw mate...or you'll have problems hitting DDR3-1100.

I might buy a few of these ddr2 kits, do the magic ddr3 conversion and sell them off at a profit!

I'm bad a$$.
Right, I'm off to watch Sopranos so go suck a lemon!

nice review had these for a while now. Any plans on comparing them against the 1066 version, to see the overclock difference?

nice review! These look a rite good set of ram!
apparently not so good if you have 2 sets....

Ordered Wed night, arrived Fri a.m... Good for 1000nhz without even trying!
i meant because they dont fit, the coolers are too big for 8gb on most boards.

You will not need 8GB in anything but a server environment anyway
Just realised I have these @ 2.2v 1030mhz 5-5-5-15 rock solid...
Think that will be ok as they are only rated for 2.1v? Might have to set to 2.1v and see what I get...

havent they got a 2.2v EVP?
2.1 is the warranty
oh 
does it not come with an EVP?

2.2 should be alright on then with their sexy coolers.. +++++++ lifetime warranty anyway and they wouldn't know they had a lil more vs going through them.
