My GeIL 2GB PC2-6400 CAS4 Dual Channel Kit (MY-058-GL) Overclocking Experience.......

onetimeposter · 18 Aug 2006 at 21:34

On badaxe 1333 strap forces 667 mode on the memory to 1:1, CPU-Z reads it wrong. It also relaxes internal latency on the chipset to the point most micron or elpida dimms will do 1100+ very easy even with tigher timings.

AM2 is a better platform to test DDR2 while we wait for RD600 which has independant memory overclocking.

Just thought I would add this so you are all aware of what the straps do with intel chipsets.

Ive got 2 x 1GB of the 6400 memory and on my new system it reports at post as PC-5300..

Ive altered the timings in the Bios as 4-4-4-12

ASUS P5W DH MB/E6600

What elese do i need to do?

edited to add, i entered the bios again and altered the memory to 800MHZ, rebooted and the machine just restarts as soon as it reaches windows.

Same story as mine - Initially it didn't start at 6400 so I set that in the BIOS, but as soon as I change the timings to the rated 4-4-4-12, it doesn't get into windows. Voltage stated on the chips themselves is 2.1V.

rich1231 · 19 Aug 2006 at 10:14

So if Asus Probe thing and the bios say the ram voltage is 1.8v, i need to up it to 2.1v?

Does anything else need to change to up it?

Im not sure of the relationship with Ram speeds to FSB and main voltages to specific voltages given to other components.

Gangster · 19 Aug 2006 at 10:53

I set my fsb at 400, with a memory multi of 2.50.

Set 2.2v (0.4+) and 5-5-5-15 and left the other mem settings on auto.

I got ~600% result from Memtest at these speeds, i felt pretty confident that the memory is stable at these speeds.

Pic:

Basically if you cant get your ram near 1000mhz or any high frequency, use your memory multis to see if its the fsb limiting you or the memory.

...Hope that helped someone? hehe

Why Overclock

Hi Guys,

Now I seen you lot argue about overclocking and getting this RAM to overclock to the highest Limit.

I recently got Married, and you know what life outside the computer world is slik. Saying that, before I used to live inside my computer because it was so swell.

I never overclocked any CPU or RAM in my life. I have seen a freek overclock his Celeron 1.4Ghz to 4.0Ghz cooling it with liquid Nitro. Anyway enough about my life story....

With regards with these rams am a bit confused.... :confused:

Why overclock????

Do you guys do it for the challenge or just to mess it up?

You know overclocking can reduce the life spam of the product.... or does'nt it?

With the fast hardware in the market at the moment... How faster do you want your hardware to go? Do you need that much power?

Am planning to do a major upgrade soon, however I bought these Rams because the looked cheap & Gibbo said they where good. My plan to upgrade would be in the next 6 months or in line with Windows Vista when it comes out.

What do you think, how far do we need to go to get what we want?!

Shall I wait or shall I upgrade now.

Am just wondering if these rams might be faulty too??!! God 4 Bid

I was worried about the same thing so Im getting these exchanged for good old corsair 5400C4... you cant go wrong with corsair... however this does NOT mean that GEIL ram is defective in any way... i just want some piece of mind and wont be overclocking anyways...thus corsair is the way to go

Well I do overclocking for fun, but this ram will not run at it's timings that it should from the factory, so overclocking is out the window.

Overclocking can be great fun it inreases the PC speed to another level provided you buy the right components.

With regards to your ram I would test it soon to make sure it is OK otherwise you will be out of time to return it if it is faulty.

Abz · 19 Aug 2006 at 12:50

Yeah corsair make qulity RAM, am currently using some for my current system... look at sig. Bad Boy Ram they are.

With regards to my upgrade to go with my Ram wanted the following:

Intel Core 2 DUO E6600
Asus P5W DH Deluxe
ATI Radeon X1800 GTO or XT
Maxtor DiamondMax Plus 10 NCQ 80GB 6V080E0 SATA-II

Already have 480W PSU Type R.

Am hoping the Ram will Run at 4-4-4-12 at 800Mhz... Will it?

Slightly off topic but i think you need to get your PSU changed since the Type R doesnt have the right power connector for Core 2 Duos..at least thats my understanding...so u should definitely check up on that...

Abz · 19 Aug 2006 at 13:06

You Joking !!!!! I only bought it recently :eek:

Can someone confirm please, if not, will it be ok for AM2 Mobos.

Also What about the other gear am planning to get?

Quote "Its the first kit I took at the warehouse, from my years experience when you get a thousand modules all from the same batch they all overclock within 1-2% of one another. Plus I am a busy man, I don't have time to test each individual kit."

Maybe this ram is different to every other then as it's now becomming even more obvious that is not the case.

I would be jumping through hoops if mine were within 30% of the kit you tested.

I have a the Hiper type R 580w running with a Gigabyte DQ6 with the F3e bios and all is well so far with the Geil RAM.

I have had the set the RAM multiplier manually to get the RAM running 800MHz and also set the voltage to 1.9v as it was defaulting to 667 MHz

I haven't adjusted the timings as yet but I will.

I also tried this RAM in the Asus P5B wifi deluxe sometimes it would boot and sometimes it wouldn't but was very unstable with any BIOS.

If you’ve got an Asus P5W DH, don’t get these Geil unless you are willing to run everything at defaults AND 1:1 FSB:Mem ratio. The problem lies with both when you decide to overclock.

The Geil has this dumbed-downed excuse of a PC-5300 factory setting to make them “compatible” with most motherboards even though they can run and are sold as PC-6400. This means your PC-6400 will be set by the mobo to PC-5300 [or less if left to the Asus crapola] unless you decide to change them from this SPD setting to what you want. That’s where the Asus becomes problematical. Due to the myriad of interlinked settings, mostly to hide deficiencies in a relatively oldish design, as the P5W DH is actually an old man asked to do a young man’s job [a plunderously expensive stop-gap “upgraded” P5W XX until the newer designs are available and they tart up this old man by using such misnomer as “Digital Home” and many yankee-type of bent-nosed “O-matic” nonsense], the minute you change from default/Auto to “what-you-need”, it starts having fits. "Ah-sorr, we at Ahsus knows best because Intel dictates so". That's what you get from a monopoly [of chipsets].

The main problem, as highlighted by “Tony” from the link given by “onetimeposter” at post #101 above, the NB straps play havoc when you can’t minutely adjust the FSB:Mem ratios. This has been the main complaint about Asus and mem adjustments. Why aren’t these Geil tested with the Asus other than the limited performance Intel board? [vmods, “I am currently using the Intel now”, "the boss won't let me use other stock", etc are not applicable to this discussion]. You want to use a cheaper low multiplier/high FSB OC E6300, you need very good memory and the cheaper Giga D3. You want low FSB/high multiplier E6700, you can then use the Geil because then you can use Auto/defaults with the Asus. But suffer the PC-5300 setting and even higher latencies. A joke.

I can get the E6600-on-air + P5W DH + Geil PC-6400 to run @ 3.45GHz at everything Auto but with [email protected], [email protected], PC-5300. It will do the above with PC-7xxx but it will crash on stressing [4:5 ratio]. Now, if the Geil is set to PC-6400 at the factory [SPD], I can Auto the mem setting and it WILL do lower latencies and not x-6-6-18. This is because the Asus will change the NB straps automatically to "havoc-mode" when you change anything from Auto [and this is not to mention that PEG-link-O-matic/JMicron crapola]. Moral of story: wait for better mobos and keep those Geil until then whilst fuming in silence. Selling the Geil is not OcUK's fault but if they pushed the sale, then it's their fault, morally, individual lucky-strike CPU/mem/mobo notwithstanding. Come the day when petroleum is £300/litre, that Merc S55zzXXLL which will cost you a mere £2000 then, is only for displaying, not enjoying.

Abz · 19 Aug 2006 at 16:09

Thank you for that :confused:

fine poetry :rolleyes:

But the information is useful. I always used Asus and find it the best so far.... but I will wait for better boards to come out by Asus that can support this Ram properly.

Also perfer a motherboard with 2 IDE ports for my old HDD's.

kimandsally · 19 Aug 2006 at 20:13

Hi Gibbo re"P.S. Regarding CustomPC, check out position 17 - You will see thats an older result I submitted but then check out all the ones behind me, most of them have faster clocked CPU's due to extreme cooling or H20 yet they can't beat my score. What is your name/position on the leaderboard please?"

I've done a Custom PC run today when my Corsair arrived to replace this faulty Geil, position 7 at the moment, might do a raid set up and water cool it next week if I get time.

Have a look at my spec, I think it's quite reasonable considering the kit I have no cherry picked bits here.

Jabbs · 21 Aug 2006 at 14:23

Well as odd as it sounds i can run higher on my other ram G.Skill LA pc5300 than i can on this Geil 6400, memory is running on me G.skill stuff at 860mhz with 5.5.5.15 timings and the cpu is happy at 3 gig.

When i use the Geil at the same speeds i get errors after like 30 seconds using the go program but on the G.Skill its happly running along atm 30 mins, i do know this too early to gauge but i will see how it goes.

What vdimm are you giving the Geil? Mine is stable at 830Mhz, 4, 4, 4, 12, @ 2.1v. I haven't tried any higher yet, but I'm at my initial target speed of 3Ghz (stock vcore)

so anything more is a bonus.

Jabbs · 21 Aug 2006 at 15:31

The memory was on 2.2 volts on vdim but i am running 4x512k sticks of the geil and maybe thats the prob. but i was getting errors with go on 2.8 gig on them which was smack on 800mhz so no overclock.

This G.Skill 667 is 1hr 40 mins through go with no probs so far with 860mhz ram speed so not sure what to do for the best, oh the G.Skill is 2x1 gig sticks.

Sir Random · 21 Aug 2006 at 16:47

You could try running 1Gb at a time (2x512Mb sticks) to find out if one bad stick is holding back your overclock.

Using all 4 slots means more work for the mem controller, so that could be holding you back too. Running just 2 sticks at a time would also rule that out.
