[MemoryReaction] G.Skill F2-8000CL5D-4GBPQ - Low in cost, high in speed!

[Spyrus]

I wonder if any 2x2GB@1000MHz kit do not use Powerchips...

[EnJoY]

All on Auto.... should I mess with them or leave them be? Its running perfectly so would I gian anything by changing the sub timings?

Try and get TWR, TWTR, TRRD, TRPT as low as you can for better performance. Set TRRD, TRPT to 5, and the other two to 10 and just go down 1 increment at a time on each while memtesting 10 passed test#5 to see where your limit is.

[Spyrus]

Subtimings worked for Abit IX38: TWR = 8 TWTR = 4 TRRD = 3 TRP = 3

On Asus Formula 6-3-3-3

Interesting, recently i have been retesting one of my 8GB set with new BIOS on P5K Pro which at last allow for manual higher tRFC. I set tRFC to 60 and run Linpack 64b 30k as my usual test. After a while i noticed Linpack produced some unusual errors -very small Residual (Norm) deviation from average ( it always failed on me with unacceptably large residuals before). This is not necessary a fail but may be of strong indication of those. I also noticed the fan is not blowing over sticks and they had become very hot. I remounted the fan over them, test still in progress, but since then no error have popped out. Probably this memory is very sensitive to overheating? And Linpack 64b seems to be very sensitive to small errors, as usual. I had ran overnight Memtest86+ previously, same setup, no errors.

I bumped up my OC a bit. This rig is rock solid @ 3816. The memory is running @ 508 now

[ShoNuff]

This memory is awesome! Given the new low price I jumped on two kits. Thanks Enjoy and eva for the reviews.

Currently playing with Vista x64 and I like it. Looking for a way to tweak Vista's SuperFetch to take advantage of the surplus of ram available.

Nice stuff nonetheless!

Help me!
my F2-8000CL5D-4GBPQ are stuck at 933Mhz
i have tried 2.0, 2.025, 2.05, 2.075, 2.1 volts
timing on auto
none of these setting can get my above 933mhz
anything above 933mhz, my system wont post
i expect it to run at spec, what is wrong with my settings?

my system:
Asus Striker Extreme BIOS 1503
2X2gb 8000cl5d-4gbpq's in slot A1 and B1
Q6600 B3 @ 3Ghz with stock cooler
all mem timing on AUTO


thx

Raise manually tWRWR ,tRTW,tWR
I have read at G.skill pc8500 threads than nforce 6xx cannot play with them i hope i am not right since yours are 8000

I have a Asus P5BD and have just purchased G.Skill F2-8000CL5D-4GBPQ Kit thinking they be great for overclocking and were cheap. I hear alot from users they easily do 1066 5-5-5-15 at 2.1 but i cant go higher than 900 with this P5BD. I ran them at 2.0. 2.1 2.2 highest is 933 now. Are they too good for this board or something? Is it the board? They wont even do a 1000.

[EnJoY]

It's a TRFC issue most likely. Leave TRFC at AUTO.

@PkG.1337

Hey seems you got the same problem i have. Stuck at 933. anything above 933 doesn't post. thanks i try the T settings.

i thought 1000 was default. surely they should come up at default spec without messing with the t settings? seems like 800 memory to me.

i'm using low FSB and higher memory frequency and still 933.

Could just be a problem with the P5B. Try PMing G.SkillTechnician here on the boards, he's in the G.Skill support forum and he's posted in this thread as well.

Very true. Remember i had a long subtle instability problem with all my sets (8 total)? Turned out it was tRFC! Even 52 was not enough. 55 solved all issues.
I would have found this earlier but ASUS limited tRFC to 42 max. Only in recent BIOS for my board they added wider selection of values.

[markymoo]

ok here's an update.
i been away a year from overclocking and was using the 1004 bios 1/1/07 and flashed it to 1219 and no different. i tried swapping both sticks from the yellow slots to the black slots and same result.

there is no setting above 42 for TRFC and so i can't select 52 or 55 and no seperate auto setting for TRFC and the rest. I selected a new FSB 290 and ran the memory at 967 and turned off manual memory settings and set it to Auto Tune and it posted lol (so much for manual tuning) and this posts and is windows stable. i believe i could do this before i flashed as i didn't select this FSB before but 300 to try and do 1000.

so i would seem that the memory settings of the P5BD are lacking like on the newer boards but 967 is better and closer to a 1000.

i try contacting G.Skill, thanks

[markymoo]

ok i got the memory running at a 1000 on the P5BD now at 300FSB. Auto speed tuning on. i set PCI to 110 and turned off C1E that did the trick. the memory heat spreaders feel very cool so it looks promising. looks like it was me not the board or the memory.

on post the memory is displaying as PCI-7100 interleaved.

$100 for 4GB of memory....astonishing!

Amazing, i know. I just hope they're as good as the review say they are

[TEDY]

they're i get 550 5-5-5-x at 2.1v

[markymoo]

more good news got this memory running at 1170 at 2.1 am very happy cookie. memory bandwidth 6.6Gb/s

[Underwater Mike]

How would you compare these the the OCZ sticks? I tend to be biased toward OCZ, but they seem to be the same chips, correct?

[Spyrus]

Can you post a memset screen?
Is that on P5B Deluxe?

Wow! Screen shots w/ superpi 32m please.
