grim, his is a XIP


Nice review enjoy. If possible, a 4-4-4-5 run would be sweet.

I have the PK's and they perform very similar, just not as great as those

does that mean non-xips don't review stuff

I'm testing 5-4-3-10-3 right now with great success...I'll post results tonight before I hit up the parties for thirsty thursday lol.

4-4-4-5 didn't gain anything over 4-4-3-5 as I mentioned in the review.

Final piece of the review has been posted along with the conclusion and verdict. Thanks goes to G.Skill for the review opportunity.

Hmm would a brand new DS3 be able to boot with these RAM?

I don't see why not, although I don't keep up with DS3 updates/info. However, to me, they would seem like an ideal fit given that Gigabyte has typically only had issues with Micron based memory.

Just about all ram will boot now on the Gigabyte 965/975 boards. The only boards that had problems were the older revisions, right when core 2 came out. A bios that came out around September fixed the problems. All boards in the past few months have been shipped with a newer bios that doesn't have the ram problems.

Nice review EnJoY and nice RAM G.Skill

I'm curious, what sub-timings were used?

[EnJoY]

As I said in another post, I switched up the timings quite a bit during testing. In my next review, I'm including MemSet in the screenshots to show the other timings.

I believe for high clocks I used 8-10-9-12, but 8-11-10-13 could also be used if needed. For lower clocks, I was able to use 5-10-7-11.

y did you use large in orthos and not blend priority 9 when you are trying to stress the ram?

My experience is that this stresses the ram better than blend. Also, I didn't bring the priority any higher than 3 so that I could use my pc while it's testing. I feel that just by me using all my daily programs while priming that it's almost as good as running a higher priority, while still remaining productive. Admittedly, running priority of 9 would be best, but frankly, if I were going for guaranteed 100% stability, I'd be running the tests for 10+ hrs, and then you'd see a review from me once every 6 months haha.

Thanks for the review. Actually have 4x1GB scheduled to be delivered this week, based on a recommendation from a friend that had a 2GB set running @ DDR2-1000 @ 4-4-3-5 timings (2.1v).

We'll see how it does. Right now I have a 2GB set of Firestix PC2-8000 running in the box @ 4-4-4-10 (2.1v). These are D9s, so are also very good sticks of ram. It'll be interesting to see how the ProMos match up against the D9s. Reason for the proposed switch is that I could get 4x1GB of these G.Skills for $250 vs paying over $300 for another 2x1GB set of the Firestix. So, unless the Firestix are hugely better than the G.Skills, bang-for-buck is solidly in the G.Skill corner.

Heya!

i got the same memories, they seem to be very good!

Well you can see my PC configuration in my sig.

I dunno why, i cant really achieve the 1000 mhz barrier, nor close to it, now.

I remember i could run a 990 mhz with some modified timings, and some 2.4 voltage, but now mostly all i can do is 950, 960 with unstable behaviors, and @ 2.3 or even 2.4v.

I use it everyday in my OC´d 631 P4 @ 4.0, with DDR2 @ 900 @ 2.1v and stock timings (4-4-3-5 @ 1T).

I dunno if i killed my memories with tests, or whatever, but i remember to see some freeze bios screens sometimes, when i used to try to push it further than 1000 mhz, and lol, really had to remove motherboard´s batery to be able to start the system and BIOS again.

I dunno if the CPU has anything to do with it, i mean, if a greater CPU(Any C2D material) will allow me more OC from memories(i know better results will come for sure), or whatever, but do you have any idea of why i cant just do the same as you did(2.25 voltage, 500 mhz, stock 4-4-3-5 timings)?

i can imagine if cpu has a great factor on that, but im not sure...

I will get a C2D soon, maybe the E6600, just saving money for my GTS videocard and so i will get it.

But well, im running very stable @ 4.0 in P4 and stock timings and 2.1v, @ 900 mhz.

The only strange thing is that 3D mark 06 doesnt complete a bench test, it bugs in the cpu test stage, and closes the program. This happen, while orthos can rock it for over 12 nonstop hours, trouble free.

And also gaming is very stable, havent find any restart of OS or anything, even after hours of gaming stress.

Any tips from anyone on how good or bad my hardware is atm, i mean, if i killed memories or whatever?

[dinos22]

you have to change your command rate to 2T to go further

[uwackme]

Are these rams the same as the current ones at Newegg going for $105?

[Reefa_Madness]

uwackme,

Newegg should have both Promos based HKs and PKs. If you confirm the part number, then yes, they would be the same stuff.

Their HZs are Micron D9 based and are also very affordable, now that D9 based stuff is down in price to where it could just about be considered value ram.

[Jaminus]

Promos memory has had a bad rep around overclocking forums, at least compared to the D9. But with all these reports of D9 sticks dying at 2.1 or 2.2V after a few months, I'm strongly considering the G.Skill HK. Do any other manufacturers (OCZ, Crucial, Patriot) offer guaranteed Promos high-end memory? I know some Corsair XMS is Promos, but I've heard too many bad things about the Corsair RMA procedure. I just want stable memory with good manufacturer warrantied specs. Crazy super-high overclocks would be nice but I'd rather my memory lasted for several years without dying at manufacturer spec'd voltage.

Have there been many reports of Promos based DDR2-800 CAS4 memory dying or is this issue only affecting D9? Also how hot does the HK run @2.0-2.1V, would a fan blowing on the memory be optimal at these voltages?

Seeing these chips run stable at 890mhz 4-4-3-5 2.0V is impressive. If this is what the G.Skill HK typically can do, that makes the Promos very appealing. I care more about moderate overclocks at nice low voltages for long-term stability to minimize heat and maximize the life of my computer. Is this 4-4-3-5 memory definitely faster than the 4-4-4-12 HZ, at the same frequency with all else equal? I noticed the subtimings listed in the G.Skill subforum are a bit different between the HZ and HK, so I'm wondering if there is more to memory latency than the base timings.

[Noob-ftw]

I had them at DDR2-1000, 4-4-4-12 with 2.25V and heat wasn't an issue.

[DevilCry]

I have them on a amd board 790fx.They were at 1066(4-4-3-5) benchable with 2.35.

Nice cheap sticks

Very nice sticks.

Dude you got too lucky!

I need 2.4v on mine to scale up to 1150 mhz 5-5-5-15, or 2.3v for 1000 mhz 4-4-3-5!

You sure you have the HK memory? Lol, just looks too good to be true.

With two pairs installed I can get 1000 mhz at lower fsb frequencies, but over 475 mhz fsb 1:1 they BSOD.

Nice!

Nice!

HK can more on 2.3v-2.4v ? how you think
