New G.skill PC6400 HZ 2x1 GB OC Report

[Xtreme Addict]

In advance I would like to apologize for my bad English

Today's subject of review is a set of G.skill memory, sold in new style heatspreaders (tomorrow I am going to include some photos ). Memory is based on Micron D9 GMH IC's.

I had many of G.skill HZ series kits in my hands, starting from old ones without EPP support, ending on HZ PC8500 (GKX). HZ series always blinds, as they are the most prestige line of G.skill memory and they overclock like hell

Testing rig:

- E6600 B2, crappy one
- Asus P5B Deluxe (1101 bios) - NO MOD & MSI P35 Neo-F (1,21b beta bios) - NO MOD
- Tagan EasyCon XL 700W
- MSI Geforce 8600GT

Some photos (only sticks).









And naked



Asus P5B Deluxe

3-3-3-10-6-42-14-14-15-14



4-4-4-12-6-42-14-14-15-14



5-4-4-8-6-42-14-14-15-14



It is absolute max on bios 2,45v (besides CL5, as 600+ MHz my mobo is limiting). But results are very good for a such cheap ram modules Don't bother with subtimings, as they are very loose to reach more MHz

And now it's MSI turn. Tuning up alphas to reach the highest possible Superpi32M stable MHz's The bad point of this motherboard is memory "wall" on 580 MHz stable... But clocking CL3 is quiet pleasant activity. So turning on some more voltage - 2,9v in bios (real about 2,82, but I shall meassure it with multimeter tomorrow morning). On "normal" motherboards lower voltage (as it overclocks memory very inelegantly) would be used, but it is the only mobo I dispose with higher voltage then 2,5v

470 MHz 3-3-3-12



I think it's quiet above averege with so cheap and low binned sticks

With regards Michael

To be continued... I hope so

They are great ram. I got a set to help me diagnose issues with OCZ I was having, turned out to be timings/motherboard.

Anyone want to buy a set PM me. I want to get a second OCZ set for 4x1G matching.

Nice review Miro, great clocks.

[ZoLKoRn]

Nice!, if run timing at 3-4-3-x How max frequency of RAM.

[RPGWiZaRD]

I'm really tempted to upgrading right now due to

1) Amazing DDR2 prices! Especially this 2GBHZ kit for only 110€.

2) G0 C2D stepping CPUs appearing on the market. E6750 2.67GHz is listed as only ~180€ in Germany (E6600 is still 188€). xD

I wonder what does those sticks handle with a more 24/7 friendly vdimm such as 2.25~2.3v as that's the highest I'd probably personally go. At least I know a person running his at CL4 @ 511MHz at 2.3v which is quite OK IMO.

[Xtreme Addict]

It was just beginning

485 MHz CL3 SuperPI32M stable



And... 500 MHz CL3



I am sure I am able to do ~490 MHz CL3 SPI32M stable

[adamsleath]

teehee mine get delivered tomorrow

[Brother Esau]

Cool, I just bought a set from Egg Head and will be here tomorrow nice to see that they are all that and for $104.00 too!

[joker2040]

I just bought some of this a few days ago and have been playing around with it. Right now my system at a glance is:

Pentium D940 overclocked to 4Ghz
Intel D975XBX2 "Bad Axe 2" mobo
2Gb G.Skill DDR2 overclocked to 1Ghz running 4-4-4-12

[Viss]

How much vdimm for 32M 485mhz cas3? Alplha timings from bios or memset? Seems like a nice pair youve got!

[Xtreme Addict]

All timings from bios. For 32M 485 MHz in bios ~ 3.1v, with Digital voltage multimeter it's about 3.02v. This mobo terribly overclock memory! I would like to have P5K if it had minimum 2,8v for mems I have to say that G.skill PCB is really powerfull, it struggles with 3,3v and is OK

Miravo,
What are the first 8 characters of your serial #? I've got two kits here I'd like to try to reach your results on.

72101200

[Brother Esau]

Just got mine a couple of hours ago and just got them installed testing 913MHZ @1:1 ....2.1V

Vey nice Ram indeed!

[Start]

What is your VDimm on the 3-3-3-10 one?

[Brother Esau]

Pretty sure if you scroll up thats been asked and answered allready 2.45v I believe.

[adamsleath]

got mine in; first glance the latencies are better than 9136's and at lower volts...but i'd already learned that.
just running 8001T @cas4 all other timings on auto (4-5-5-14-22)@2.15v
4-4-4-12 1T@2.22v
i'm sure i could push it's limits, but dont feel the need.
i'm happy. extremely good value ram.

[Xtreme Addict]

Yes, 2,45v on Asus P5B Deluxe

[Brother Esau]

Actually to be truthful I like this Ram better than the Crucuial Ballistix Tracer!

[killingspreez]

they perform great, i have 4*1gb of this ram!
here some screen (i didn't really overclock, no time at the moment)

[Reefa_Madness]

GSkills, Crucial Ballistix...they are both good, as well as many others...the common thread? They're all using well-binned Micron D9s, of course!

[The Nemesis]

72101200

I have a 71901200 & a 71701200 kit. I trying the 71901200 set first but with tighter timmings.

2.3v 3-3-3-10 DDR2-800



2.36v 3-3-3-10 DDR2-830



2.44v 3-3-3-10 DDR2-850

[Xtreme Addict]

Very good set and strict alphas

[Brother Esau]

I'm guessing somewhat of a compatibility issue with my Ballistix Tracer why I don't know because others are running them with success either that or I am more anal and intuned with whats what, but I'm leaning towards option A.
Actually they are sending me another board as some weird stuff has transpired with it after about a month of overclocking bliss and it running like a champ! I will be getting the cross shipped board today actually so I'll see whats what but I still think its a small compatibility issue!

But hey man for $104.00 for these G-Skills HZ they totally smoke and actually I am quite impressed with the responsiveness of them this being my first ever set of G-Skill.

I can't quite get to DDR2-1200 with these. But I'm on a DFI Infinity UltraII-M2. I'm not sure if that's my problem. Tbh this is my first pair of DDR2 so I'm not real experience in OCing them.

I hit about 1050 w/ 2.2v on mine. I think I'll try more volts soon to see if that does the trick.
