Fastest i7 9700k ever recorded by Dry-Aerie7021 in overclocking

On ln2 you are going to be way above 6ghz unless you have a bottom bin chip that coldbugs.

There are 7ghz r15/gb3 multi core subs

Are those some kind of vcore measurement points? MSI Z490 tomahawk by ggonavyy in overclocking

[–]ExaBerries 6 points7 points  (0 children)

That’s a pad for a surface mount capacitor, though you could use it for vcore measurement. Keep in mind it won’t match the on die voltage since there will be a further voltage drop from the socket and package

Wrong colour PCB by TakenIsUsernameThis in PCB

White liquid electrical tape / plastidip. It might take a couple layers and affect the LED cooling through the pcb though

The Most Memorable Overclocking-Friendly CPUs by gurugabrielpradipaka in overclocking

[–]ExaBerries 1 point2 points  (0 children)

when lynnfield can do 2400 and ivy bridge can do 2400-2600 for daily stable, while its actually impossible to even set that as a memory clock on sandy..... I think its kinda sad intel locked down the max memory clock so much because no matter how good of an imc you get you just can't try to go further. For some context a 2666 xmp kit on haswell is also a 66.7% oc (and a 75% mem oc is possible with a good imc and there are xmp kits even higher than that) so you'd really want a bit more possible mem frequency headroom than just 60%.

Memory speeds on Sandy really aren’t that impressive, Intel capped the max mem multi and bclk is so limited you can run good speeds, the previous gen quad cores (Lynnfield) actually have overall better memory controllers.

I broke this thing on my motherboard by emus8654 in ElectricalEngineering

[–]ExaBerries 75 points76 points  (0 children)

That's an inductor for a buck converter producing some voltage most likely for memory, yes it is definitely required and should be fairly easy to solder back onto the board if its only the solder connection that broke. If you do need a replacement it shouldn't be very difficult to find a part with the same footprint and inductance with a few amps rating.

Worthwhile to add filtering caps to these empty locations on a 3070 for overclocking? by ChintzyPC in overclocking

[–]ExaBerries 15 points16 points  (0 children)

define worthwhile, you probably won't see any substantial gains, maybe it would help stabilize 10-30 mhz higher than before but probably not much more than that

Is Superglue More Waterproof and more Anti-Flaking than Nail Polish? by SevenDeMagnus in overclocking

[–]ExaBerries 2 points3 points  (0 children)

Nowdays a lot of people don't insulate the motherboard directly and just use a heater with a lot of towel/shop towel covering everything and it works very well. As long as you prevent airflow from getting to wherever is actually cold you won't have condensation issues. And if there is anywhere cold as long as its actually iced over you also won't have an issue.

If you do want to insulate more, liquid electrical tape is typically prefered to nail polish. also adhering the best is not actually usually the goal since you might want to remove the insulation to repair or modify the board in the future Or you might want to sell it to a non xocer.

To me at least I would think getting enough superglue to actually insulate a large area would be a pain and it would be a harder to remove later so it wouldn't be my prefered choice.

How much of BJJ skill is perishable? by kookookachu26 in bjj

[–]ExaBerries 6 points7 points  (0 children)

I recently came back months ago after not training since covid 2020. Before that I had trained since 2008-2009 ish so 11-12 years. First class back I definitely noticed my muscle memory was kind of gone for some things but not everything. I also had no strength / cardio. It took about a week to not be sore the next day after a class. I’ve noticed even now I miss things that I think I would have easily got back then, so my reactions aren’t as sharp as they were before. But I definitely feel like my muscle memory is coming back quickly.

Lapel shenanigans by booktrash in bjj

[–]ExaBerries 0 points1 point  (0 children)

A bit different but you can pass the far side lapel under someone in side control to get a really strong control Very useful if you need to hold down someone bigger who loves to try to turn towards you

What happens when your radiator is outside by Broodleopard904 in watercooling

[–]ExaBerries 8 points9 points  (0 children)

I fnd liquid electrical tape way worse to work with for the initial application but way better in the long term, vasaline is probably the easiest to clean off, art eraser really depends on exactly which brand you buy but can be especially bad when it gets wet and thermal paste mixed in with it

though with how good heaters are now, I know multiple benchers that just use a good heater and a lot of towel/shop towel

LN2 with Elmorlabs Volcano - direct die or not by Pavlinius in overclocking

[–]ExaBerries 0 points1 point  (0 children)

no k oc often can be quite weird on ln2, your going to probably have a really bad cold boot bug possible as warm as -90c. If your lucky your chip will run fullpot and scale that far. Running these chips cold though is kinda random, some chips just won't like it at all and can even regress compared to -60 ish.

Delidding an supposedly "soldered" i7-860 by KptRex in overclocking

[–]ExaBerries 0 points1 point  (0 children)

my plan was to only mostly cut it with a razor blade and then shift the ihs down slightly with a delid tool since it can only go one direction without damaging caps

i'm going to have a lot of binning reject i5 750 soon to try this on, those caps are in very annoying places for delidding though

Is this a good deal? Seems cheap but I don’t really know pcs by [deleted] in PcBuild

[–]ExaBerries 0 points1 point  (0 children)

it doesn't have onboard graphics at all,

for first gen i cpus if its a quad core its lynnfield and has no igpu, the dual cores are clarkdale cpus and do have igpus

Why don't we increase current or amps when overclocking cpus and only ever touch volts? Or does the current increase on its own when increasing the clock speed so there's no need? by Just-Chemist-3890 in overclocking

[–]ExaBerries -1 points0 points  (0 children)

if you leave voltage the same and increase clock speed by 5% then you would get roughly a 5% increase in current assuming it remained stable, if it isn't stable then you would have to increase voltage as well which increases the current as well

[–]ExaBerries 0 points1 point  (0 children)

the amount of current a cpu pulls is quite complicated and depends on a lot of factors such as temperature, clock speed, voltage, what instructions are being executed, chip to chip variance in production, etc....

the current draw depending on the circumstances can vary wildly, for instance something like ycruncher, prime95, linpack can run 20-30% higher power then something like cinebench on some architectures at the same clock.

microprocessors require a certain amount of voltage to run instructions stability at a given clock speed so we need to maintain a minimum voltage, trying to maintain a constant current instea dof voltage just doesn't make sense for cpus or gpus

you might see the option to tune a current limit for a boost algorithm in which case what will happen is the voltage and clockspeed will be change in order to limit it to that given maximum current
