This is certainly not your problem, only posted to answer your question. Here is a picture of the settings to change for future use. You can also get the setting to change from CPU-Z.

I am getting solid 7250~ mbs now. I was getting like 5400~ mbs I believe.

Sure - but the OP is attempting to first reach the 5400 mbs. Capish? He says he is getting ~2500 mbs.
Any memory bandwidth beyond the CPU is not useful anyway, not important and is not why your rig feels 'laggy'...
Clearly the situation is with your mobo as memory migration gives constant results.
This approximately 1/2 memory bandwidth could be explained by single-channel memory operation...?
I would wonder about your BIOS settings and believe there are some answers to be found in there.
But it's a strange one, eh guys?
Regards
 
Very strange. I did some benches with single channel and dual channel earlier, and I didn't get anywhere near double the bandwidth. As a matter of fact the increase was seriously disappointing. Also, he has installed his RAM in a few other systems with proper bandwidth results, so we have to assume has has them in the right slots.

Edit: Based on his CPU-Z screen shots he has them in slots 1 & 3, which is correct.
 
I will take a picture of my settings and how I have them set when I get home tonight from work. You will be able to see how the new bios f7b looks as well compared to the old ones. It looks alot better trust me. The performance is the same as the others as well with my testing. They might have even fixed some issues as they don't always say everything that they have fixed in their bios upgrades.
 
F6 apparently just fixes problems with the PCI ROM. Lower than F5 should be updated. As I said I would update before RMA anyway, but don't do F7b.
F7b is a beta BIOS. Apparently the important update in that BIOS is the Yorkfield support. If you don't have a Yorkfield then it would be wise to wait for the official release to avoid any bugginess. I know you already have it, I was referring to the OP. The bottom line is, flash the BIOS if you need what is offered and never flash to a beta, unless you really need it.
 
The new format is probably nice, I will update as soon as they remove the beta designation. I shouldn't have to wait long.
 
OMG what is it with people not reading what I post lol. I have it on my pc there is no issues with the bios. I have tested and tested again there is no difference they never put everything that they have fixed on the explanation of the new bios. They could have made improvements to the memory timings as well as I have noticed some bugs being fixing in it like the prd precharge glitch that there was in the last four that they had put out.
 
OMG dude :bounce: Maybe you should read my earlier post where I said
I know you already have it, I was referring to the OP.

Do you know that your configuration is the same as mine or the OPs? Obviously you don't. Take a Valium. If the OP is trying to clear a problem it would be foolish to install a beta BIOS update. F6 works just fine, I know because I have it on 3 machines right now. I can wait a week or two for that BIOS to be released from beta. So get a grip on yourself.
 
I'd have to agree, I also have a similar configuration. While a beta BIOS could potentially solve a problem, it's more likely to cause more problems then solve. After all, there is a reason why it's still in beta.

Also, I knew the memory improvements were in F4, however if your updating your BIOS you might as well go straight to the most current BIOS (F6) as you've already started the process.

Why would they ever make a BIOS look better, though I'm kinda interested in what Gigabyte is up to, please post some pictures when you get back from work. As you can see I don't install beta's, I take stability over everything else.

Ok here are the pics of what the new one looks like and you can see what my settings are that I tweaked as well.

Ok the static tread phase adjustment is the one I noticed is not glitching out any more. That thing used to jump around to different numbers all the time under the auto settings part. It hasn't done this to me since I flashed it. I think that they added the refresh to act delay as well. I don't think that was there on the old ones. Because that is one of the settings I had to change with memset before I flashed it I swear..
 
I also forgot to mention that my memory auto timing when left on auto used to be wack but, now they read the way they should as far as the right timings at the right volts and what speeds and what not. I wll also add this and this is the wierdest part,,,, Cpu-z actually shows the RIGHT VOLTAGES ON THE CPU NOW!! That is a miracle by itself if you ask me lol.
 
My guess is that the mobo is doing you a favor and ignoring some of your insane settings. The only one that I noticed immediately is a tRAS setting of one.

Maybe it wasn't the F6 BIOS that was causing the problems but the board trying to function with the insane timings. See the following quote.

techPowerUp! :: Memory Timings Explained

tRAS Timing: Min RAS Active Time. The amount of time between a row being activated by precharge and deactivated. A row cannot be deactivated until tRAS has completed. The lower this is, the faster the performance, but if it is set too low, it can cause data corruption by deactivating the row too soon.

tRAS = tCL + tRCD + tRP (+/- 1) so that it gives everything enought time before closing the bank.

e.g.: 2.5-3-3-8 The bold "8" is the tRAS timing.

(The 2.5-3-3-8 figure is just an example for memory timings.)

That is because the mobo is ignoring at least your tRAS. If it didn't you would crash immediately. You might want to do some research and verify and tweak your timings.
 
I swear man you suck lol. My settings are sticking your motherboard won't ignore settings it will crash period no second chance I will ignore,, crash. I know this you can trust me on that.
 
Ok, rock on.
 
Lol ok you were right sorry. I could have sworn it listened to me the last time I checked it. I'm sorry ok I said it lol. I did get it to set this though.

I'm sorry 😛
 
LoL truehighroller, that's like the world's most serious E4400 memory - you've got that stuff running 1183DDR? Heheh...
So it's a good mobo then? What's going on with OP's rig then, I wonder.
He's not set up right; I say it's BIOS setup.

Hey Guys :)

One of the first things I did when I installed the MB was too update to the F6 bios update. So its that I've been running on since I installed the O/S.

My feeling is that it has to be bios related. I have tested my memory in other peoples machine, who also run gigabyte boards and its scoring 6000+ in the memory bandwidth tests on Sisoftwares Sandra. I can even take their memory, put it in my system and watch it drop to 2500 too.

I've looked over the bios settings alot, but I just dont know enough to spot anything beyond the obvous. So if its a setting, I dont know which.

I have the memory for sure in dual mode. I tried both slots 1 & 3, and 2 & 4, but that did little for me.

Would it help if I hit the Optimised default option again to make sure everything is set right ? I actually had to hit that option the first time I installed the board because I *thought* i had screwed up a fan control setting. So did i accidentally set something low or off when i used the optimised perhaps ?

Again, thanks for all the help. Gigabyte has been close to useless. They want me to Rma the board .. and this is my second one of these in 6 weeks, and I dont want to have to Rma if i dont need too. 2 to 3 weeks without my pc makes me pissy :)
 
Did your friends have a Gigabyte P35 mobo? Give me a link to your ram. Not just the fact that it is PC6400. Your settings appear to be correct. You can cetainly try Opt def again, but I thought you already did that with no success. Opt def should work. Link to your RAM.
