Higher bandwidth is better. 8,000MB/s is better than 7,500MB/s

As far as overall latency, lower is better. 35ns is better than 40ns

If you have 2 sets, the lower frequency will be better.

Thank you

I used my 8GB of F2-8500cl5d-4gbtd (2 sets) using timmings 4-4-4-12 auto the others at 800MHz 2T 1.8v without any problem

I want to ask you if I can use 1T with this memory and if yes do I have to put more voltage?

[Tradesman]

Try it, it make take additional voltage, would suggest a tad to the DRAM and a tad to the MC voltage

[el_arantis]

Thank you for your vast response!!
Will I see any performance if I acheive 1T or it's not a big deal?
More over what voltages do you think I should use?

Thank you once again!!!

[GSKILL TECH]

It's not a big deal, but 1T is considerably better performance. With two kits, rarely is 1T stable, but you can try.

1.90V should be fine for DDR2-800 CL4, then see if 1T can work.

Thank you

With 1.8v I have cl 4-4-4-12-19 2T
Is it better to leave it 19 or set it to auto (24)?
But for 1T will only 1.9 be OK or I should raise it further?
Thank you once again!

[GSKILL TECH]

You just need to test to see if it can be stable. Each kit is slightly different, so you need to test and see if the modules you have can do it. If not, just set it back.

Thank you

I bought my 2 kits at the same time so I think these are the same, but you know better
By the way with 2 kits and 1T my pc could not post so I had to crear CMOS.
If I use 2 kits at 800MHz CL4 you said that performance is similar to 1066MHz CL5
so I would like to ask your opinion about all latency values if you don't mind for 4-4-4-12.
Just to mention that with 1.8volts I had to errors with memtest86 and in-game.

My mothermoard has these settings:
CAS Latancy = ? (suppose 4)
tRCD = ? (suppose 4)
tRP = ? (suppose 4)
tRAS = ? (suppose 12)
tRTP = ?
tRC = ?
tWR = ?
tRRD = ?
tWTR = ?
tRFC0 = ?
tRFC1 = ?
tRFC2 = ?
tRFC3 = ?

Thank you for your time.

You are really supporting customers via this forum.
G.Skill will be my top priority for ram on my next system because of your support and performance.

CAS Latancy = 4
tRCD = 4
tRP = 4
tRTP = 4
tRC = 24
tWR = 8
tRRD = 6
tWTR = ?
tRFC0 = 78
tRFC1 = 78
tRFC2 = 78
tRFC3 = 78

I think you forgot a value from what I wrote.
Can you please write it one more time?
Thank you in advance.

CAS Latancy = ? (suppose 4)
tRCD = ? (suppose 4)
tRP = ? (suppose 4)
tRAS = ? (suppose 12)
tRTP = ?
tRC = ?
tWR = ?
tRRD = ?
tWTR = ?
tRFC0 = ?
tRFC1 = ?
tRFC2 = ?
tRFC3 = ?

In addition I would like to ask you what kind of better performance should I get by changing from 5-5-5-15 to 4-4-4-12?
More fps? Faster loadings? (now I am at 4-4-4-12-19 1.8v)

Thank you once again

[el_arantis]

Can please someone from g.skill reply?
Thank you

[GSKILL TECH]

Everything is quicker, the memory can respond a little faster to the CPU. It improves the overall system performance.
