Corsair 3700xms vs. OCZ 3700 Gold

[Radelon]

Update: Corsair and OCZ tests at GAT on Auto. Corsair is unable to run GAT on Turbo, but the OCZ is. So I will have those all combined into 1 reply

Test System (Constants):
P4 1.6m (defaults to 12x multi in desktop board)
Abit IC7 /w 1.5 beta bios
Powercolor Radeon 9700Pro
2x40gb IBM 60GXP in Raid0
PSB800 Strap in 1:1 or 5:4 configs (2.8v for vdimm)

Memory (Variable):
2x256 Corsair XMS3700 TwinX from GoogleGear
2x256 OCZ PC3700 Gold DC from Directron

Tests will be held at 200, 216, 233, 240 and then MAX FSB all at 1:1 ratio. There will also be a 252fsb 5:4 run used on all Variables.

NOTES: Corsair XMS3700 TwinX will not run with any sort of GAT (Game Acceleration Technology) Enabled. Therefore there will be 2 sets of OCZ PC3700 Gold DC tests. Thus showing a better head to head and also the gains from having your memory allow for GAT to be enabled. All tests will be run at the best possible allowed timings for each Memory config.


I will reserve posts for each Memory in each config, therefore having all the information be at the top of this post.

Programs used:
CPU-Z 1.18 Memory Screen
Sandra Max3 Buffered Memory Screen
Sandra Max3 UnBuffered Memory Screen
3DMark2001se Score Screen
PCMark2002 Score Screen

Below I will post just the Numbers from each config for direct comparison reasons:

Remember, all tests are run at the tightest timings each particular config will run at a certain fsb

Great stuff Radel0n!



:eek:

[emericanchaos]

great scores! go figure the less efficient CPU design gets a more efficient chipset. argh AMD will catch j00!! ;)

[BadThad]

Nice work...thanks for the benchies man! :)

[Radelon]

Thx for the complements and replies. Remember, the OCZ with Turbo GAT benchies are still in progress.

[cypher_138]

Wow thanks for the effort you put into this. It will help alot of people out. I just exchanged my Corsair 3500 for 3700. Unfortunately they did'nt have any OCZ and a refund would take like 15 days if approved minus a restocking fee.

[pscdoc]

Well ozc can run all GAT options whereas corsair cannot run any. My top with ozc is 240FSB@1:1w/F1 and manually set at 2,3,3,6 to boot. Only thing limiting me is my 3.0c 15x multiplier. Grrrrr....wait till i install the promethius. But before that we shall see wut Kingston HyperX pc4000 can do at DDR500 in this rig.

[TheGr8s1]

Now u got me wanting to retest my OCZ gold dimms. Thanks for the work. :)
CHEERS!

[TheGr8s1]

I wanna see someone do a volt mod with this memory and see what they can get outta it. Imagine 275fsb 1:1. Drool..........I'd try to do it myself but I don't have the right tools for the job yet and I'm still a newbie at volt modding.

[Nomjr]

Will the volt mod work as I thought I read that the gold has some kind of technology that limits the volts to 2.9 +5/-5? I ask because I've set my pot to give me 3.0v at 2.55 and if I go to 2.85 which should be 3.3v. I checked with my meter and it's only giving me 3.04v at any setting in the bios....:rolleyes:

[TheGr8s1]

Bummer. Is this true? Can anyone else back this up?

[mrspec3]

No I've run my 3700EL gold at 3.2V b4 in an amd system. I PM'd the OCZ guy at extremesystems b4 I got my ram and made sure they they didn't limit the amount of voltage I could throw at it

[Nomjr]

** OCZ Extended Voltage Protection® circuit protection allows modules to handle higher voltages through a novel voltage protection circuit. OCZ EVP® protected modules tolerate VDIMM voltages of up to 2.9 volts +/- 5% and are covered by the OCZ lifetime warranty if overvolted within EVP® tolerances.

from here (http://www.ocztechnology.com/products/memory/OCZ+EL+DDR+PC-3700+Gold)

Maybe one of the ocz guys will comment on this?

Then again I could just be interpreting it wrong :(

[TheGr8s1]

That's good news to hear. Thanks for the info. :)

[cypher_138]

Update: I'll take the 15 day hit to get some OCZ. THe Corsair goes back on Monday.

[SeanOMatic]

The EVP is just extra protection when running higher voltages. You can still run at 3.0 volts, etc.

[chilly charlie]

I have always liked ocz RAM Great RAM for a good price

How does this protection work?

The only way I can imagine "protecting" the RAM IC's is by putting a Low Drop Out (LDO) voltage regulator between the motherboard supplied rail and the actual power pins of the RAM IC's. (Actually, I can imagine cruder methods, but that's inconsequential.) If there is some sort of voltage regulator limiting the actual rail the RAM sees, then some might say your statement is misleading.

That was an enlightening read.

[JP_Singer]

Now I would really like to see someone compare Corsair TWINX512-3200LLPT 512MB DDR400 XMS3200 Ultra Low Latency Dual-Channel with OC7 Gold PC3700,funny thing is that peeps keep buying Corsair pC3700 when they can purchase 3200LLPT 512MB DDR400 XMS3200 Ultra Low Latency chips for $10 less and have much higher results I cant wait to post my results when mine come in I guess that's just how little everyone knows about this particular model.

Good read :)

whats the big deal, never once did i hear OCZ say they make there own GOLD chips, they said they made there EL chips. and anyways the gold ram is mopping up every other brand out there. what else you want??

[TheGr8s1]

so? what's with the fuss? I know OCZ kicks you know what.

[Perre]

I hate that I can't run my mem with higher voltage than 2.8v. Everything above gives me no boot. Damn max 3....
