when i had the surging boot problem on my old rig i swapped out the ram and bam! it would boot. with my new rig going over 4.5 ghz causes the pc not to even post half of the time. i was wondering if that could be because of my 1333 ram i see some people saying that their 1600 ram might not be fast enough when they cant get past 4.4 ish but once it finally boots it runs just fine at 4.8 ghz it doesnt make any sense to me so if some one with better knowledge of how ram effects cpu clocks i wonder how it would become a "bottle neck" of sorts

i do know that older pc's had the memory and cpu bus's linked but as is not the case with the new sandy bridge pc's so would memory speed still be a limmiting factor?
i know i have alot of questions i am going to stop typing before i confuse myself anymore. lol

Wut?

Swapped out what ram? Capacity? Speed? I think we need more information to answer this...post. But seeing as how on SB you cant overclock the bus and memory speed is only a factor of the multiplier, keeping it at the rated speeds or lower would take it out of the equation.

i was just talking about my last motherboard that my i5-750 was in it was 10666 ram and i swapped it out for 10600 both 1333 and for some reason it booted fine and oc'd way past the 3.3 ghz limmit i was having with the other ram.

im using the 10666-1333 ram in this board i swapped it out for the 10600 like last time but it didnt help so i was just wondering if maybe going to an 1600 or 2100 kit would let be get a better clock?

because i have the same exact symptoms when i tried to oc my 750 past 3.3 ghz with this ram in it it wouldnt even post and would sit there and reboot itself trying to post and by te time it does it says fu and resets bios

I still dont get it...

There isnt, that I know of a 10666 memory and 10600 memory. Just go by 1333 (the acutal speed).

What I think is the problem with your system is the two, Im sorry, Pieces of garbage PSU's you have powering your system. And before you get better ram, I would scrap those lead weights and buy a real, single PSU..

You are not giving us enough information to solve your issue. For example, on your 750, where was the memory speed at? Did you try lowering it?

Same thing here, what memory speed are you trying to boot at?
Have you lowered it?
Are the voltages set right?
Timings?

[wagex]

1333? all the voltages are correct. and there are 3 different types of 1333mhz ram ddr3-10600 ddr3-10660 and ddr3-10666 its the only ram like that idk why its like that all i know is on my last motherboard (the one with the 750) it didnt like the 10666(1333) as much as it liked the 10600(1333) there must be a difference it was the same brand timings voltages and speed just different number after the "pc ddr3", im just saying. and i have tested a few other psu's that are of better well known quality they are on my other machines i just had to put in a lesser video card to test them out but it still did the same thing no matter the config it would do that a few times and eventually boot up just like it does with these 2 crappy psu's i have a new one in the mail already even though i know they arent the problem.

=1333?

im trying to boot with the memory at 1333 with all its stock specs 1.5v 99924 timings

[EarthDog]

I see that difference now, and wonder why its there. Its 1333 speed... LOL!!1

[wagex]

lol yea i always wondered that too ;p sorry if i came off as rude this pc is just peesing me off so bad! lol to the point ive almost started smoking again lol or brought it out back for some target practice lol such a shame i got my pump and 4.120 rad in

[trents]

Here's what he's talking about, in part anyway though the run on sentence structure makes it hard to figure out the main point. As far as ram speeds the poster is using "PC3xxxxx" speed terminology instead of DDR3xxxx.

[trents]

wagex, I'm an AMD man myself but what you're describing sounds like what happens on the AMD side when people implement a high overclock but leave green, power saving, throttle-down technologies enabled in bios. Recently I was having intermittent hangs on bootup that disappeared when I disabled Cool N Quiet and C1E in bios. I'm sure Intel has their equivalent of these things.

[wagex]

yea they do have them but i tink i have them all disabled il check though :P thanks for the hlp guys.

yes i got in trouble for the sentence structure all the time in school. lol off to do some case modding :
