won't boot @ 5Ghz, damn it. need better cooler from other machine.

pumped 1.47v, should I risk going higher just to see if it will boot?

 

[d1nky]

Oh ok. Well I have my FSB at 250 so maybe that will be of some help. I normally just disable most everything including that, cuz I didn't really know for sure what it was.

How hot have you gotten your CPU with that loop? My max stable clock so far has been 4.875, and it gets to around 50c pretty quick with IBT.


I got some new memory, it's Kingston hyper x 2666, and then suddenly I couldn't get my NB to OC high enough to use it at that speed. Apparently it has to be faster than memory speed? I never had any memory faster than 1600 so it never came up. So It's at 2400.

@pipson: 4.5 is the sweet spot on mine too. It's perfectly stable there with 1.33v

my max temps so far is about 50*c and thats up to 1.6v i use prime tho, id probably be IBT stable if i tried it!

we're talking cpu/nb here arent we?! if temps allow id try 1.35v on cpunb and overclock the the cpunb to 2700mhz (cpunb has to be the same speed as ram or 3x times higher than ram base clock)

sometimes messing with the FSB you can have differeing speeds but the multiplier/divider will follow that!

max ram oc ive had was 2550mhz stable with 2600mhz cpunb and 4.6ghz cpu (11-13-13)

im working my FSB up to 250 atm so will try adjust cpu vdda - it has two settings 2.56 and 2.7v

yes! if temps allow, always make sure any of the cpu temps are below 62*c especially core temp!

and you got a great overclocker of a chip for 4.8ghz at 1.42v

mine at 4.8ghz wants 1.52v lol

 

[RCoon]

mine at 4.8ghz wants 1.52v lol

Whats the VDroop on that chip right now? You've been punishing it for a while now
Cant you get W/C block for the NB area of your board? I know you can get chipset W/C blocks but only for very specific boards. Might help out with applying more volts to the NB without it turning into curly fries.
I want steamroller to come out so I can join the club again!

I haven't tested for complete stability. It's just 'usable' stability, can play 1080P videos and play games but not 100% cpu usage stability.

this LLC is pretty good but named backwards, 25% holds vcore to whatever bios has set with a total fluctuation of 0.040v

yea im getting a new one i think maybe the steamyroller! and the next ill care for it! im just beasting this to get the 5ghz which is tough!

my mobo temps are good, NB doesnt get much more volts than stock (most are up to .1 extra max)

fuck about! i could have 5.5ghz 'usable'

whats happened to the prime only times lol

i still got to send my pump off for rma which ive not done because im on the quest for 5ghz lol may even give up on prime and do IBT but that would be easier tbh

LOL! I have never had a need to run any of my chips @100% for days together to achieve ultimate stability. Video conversion may be close to 100%. So If that thing can survive that kind of torture and game well @ 4.8 I am ok with it

Anyway for 24/7 I aim at 4 to 4.2 undervolted than stock

 

[d1nky]

im tryin 5ghz if it kills me or the chip.


ya know when you have to do something and cant fail, well thats how i feel!

I'm with you there but tried few times now and I keep getting flamed and blown a blue finger plus toooo damn hot in uk wtf

 

[d1nky]

its HOT. max ambient here was about 33*c

im impressed the cpu has maxed at 56*c at 1.6v so far. keeps building lol

ill sell this chip before it degrades so hard it wont be stable at stock.

idles at 35*c atm

CMON! i feel like putting stella in my loop for it to man the eff up!

(8350 + aegir £90)

 

[Random Murderer]

blown a blue finger

must be an idiom I'm not getting here

plus toooo damn hot in uk wtf

Come to Florida. You won't be complaining about the heat in UK anymore Lately, it's been hovering around 38C with 70+% humidity.

 

[d1nky]

LOL come to the UK, ya wont be complaining about U.S prices then........

Same here ,, id guess.

Blue finger (middle) from Os ie Bsd

I don't complain now, lol.

 

[d1nky]

well ive just been kindly informed and concurred that a lot of the people 5ghz on a 8350 arent actually prime stable, and when they say lower volts (1.5v etc) they dont say/account the LLC effect.

do or die trying i guess!

do it!

 

[d1nky]

do it!

damn this is a battle!

im meant to be working, but havent started lol

and if im having time off i should be enjoying the sun!

 

[cdawall]

Come on set a clock so I can see if the 9370 will beat it

Which core fails first?

 

[d1nky]

HOOOAH! - the outdoors is overrated tbh!

any of the cores, illegal sum outs or rounding errors. usually only 1 of the 8, followed by another.

if my cpu vcore bounces around pass 1.6v it freezes.

im trying it from all different angles, ive messed with LLC, PLL, now dropped all my other voltages back including CPUNB. im getting closer.

i may just give up with prime stable and use IBT AVX which is easy compared to prime.


ive already benched it at 5.1/5.2 ghz (physics = 10k firestrike/9K 3d11)

You clocking by the Multi or by the Core Clock? I'm assuming you're keeping to rounded figures, so why not start messing with ratios now, run the RAM at different ratios, even if it means lower speeds of RAM for a more stable clock between 5000 to 5100

Try 23 x 221, that was my magic number for 5Ghz on the 8350.

EDIT: I recommend you do what I usually do when tinkering with clocks - get a second monitor and a media PC, watch tv while clocking. It makes waiting for reboots and reset junk slightly more entertaining.

 

[cdawall]

I bet at 1.6v your VRM's are throttling.

 

[d1nky]

my vrms are pretty cool tbh 12+2 phase design and modded with fans.


i usually got my second rig next to me when overclocking, but its in bits so i may just rebuild it while i overclock!


oh i have been messing with different ratios. FSB @ 250 and ram etc lower than stock, loose timings. memtest passed. HTcpunb etc up and down!

ATM
FSB 250
CPU x 20
CPU VCORE 1.55-1.6V
CPUNB 2205 1.3V
HT 2695 1.25V
NB 1.8V OR LESS

RAM 1600 11's (2133 stock)

CPU VDDA 2.56 (sometimes 2.7)



and thanks to rcoon i got that friggin hero song stuck in my head and cant stop singing it!!

hes gotta be fit from the fight........

 

[cdawall]

Just because they are cool doesn't mean they aren't throttling. There is a chance like the midrange asus boards that you are hitting the over current protection by pulling to much wattage

that does sound possible tbh


hmm it freezes up after a couple mins every time. seems LLC influenced tbh.

Oh it is trust me Almost all modern boards have OCP built into the VRM section noting that your board lacks any crazy 7-8ghz overclocks it wouldn't surprise me if it is because of the OCP.

Hwbot shows the highest overclock on that board to be 5225mhz there is likely a reason for that. The extreme9 however is in the number two spot for max overclocks

hmm it freezes up after a couple mins every time. seems LLC influenced tbh.

That screams VRM's either throttling or causing a massive undervolt.
